CONVERT 14 TOOLS
Convert PNG to JPG Transparency is composited over the chosen backdrop color (white by default) and saved as JPEG. 01 Convert PNG to WebP Re-encodes the image into WebP with adjustable quality. Transparency is preserved. 02 Convert PNG to BMP Saves the image as 24-bit BMP without an alpha channel: transparency is replaced with a black background. 03 PNG to Base64 Encodes the image into a base64 string for embedding in code or styles. 04 PNG to Data URI Builds a full data-uri (data:image/png;base64,…) for embedding in HTML/CSS. 05 PNG to HEX pixels Shows all pixels as rrggbbaa hex values — row by row, space separated. 06 PNG to Bytes Lists every pixel as four decimal bytes (R G B A), one image row per line. 07 PNG to RGB Values Lists every pixel as rgba(r, g, b, a), one image row per line. 08 Base64 to PNG Decodes a base64 string or data-uri back into an image. Paste the string on the left. 09 Data URI to PNG Decodes data:image/…;base64,… back into an image file. 10 HEX pixels to PNG Assembles an image from rrggbbaa hex values (space separated). Set the width — the height is computed automatically. 11 Bytes to PNG Assembles an image from decimal RGBA byte numbers (any separators). Set the width — height is computed automatically. 12 RGB Values to PNG Assembles an image from rgba(r, g, b, a) numbers. Set the width — height is computed automatically. 13 SVG to PNG Decodes SVG markup into a raster image. Paste the SVG code on the left. 14
TRANSPARENCY 20 TOOLS
Outline PNG Adds a colored ring outline around the opaque content with the chosen thickness. 01 Find contour PNG Leaves only a line along the boundary of opaque regions in the chosen color and thickness. 02 Remove color from PNG (make transparent) Makes all pixels close to the chosen color transparent. The tolerance sets the allowed deviation as a percentage of the maximum color distance. 03 Circle Mask PNG Cuts the image into a circle. Diameter is set as a share of the smaller side. 04 Square Mask PNG Cuts the image into a rectangle with sides as a share of the smaller side. 05 Star Mask PNG Cuts the image into an n-pointed star with adjustable inner radius and rotation. 06 Wavy Mask PNG Cuts the image into a wavy-edged circle: radius is modulated by a sine with chosen amplitude and frequency. 07 Remove alpha channel PNG Composites the image over a white background and saves without transparency. 08 Set alpha channel PNG Assigns the same opacity to all pixels; colors stay unchanged. 09 Extract alpha mask PNG Turns transparency into a black-and-white opaque mask. 10 Round corners PNG Clips corners by a radius set as a percentage of half the smaller side. 11 Invert alpha PNG Opaque areas become transparent and vice versa. 12 Remove background PNG (smart) Removes a solid background: by color with tolerance, outer regions from the edges only, or every matching pixel. Can smooth the boundary. 13 Thicken PNG Expands opaque areas by the given number of pixels. 14 Thin PNG Shrinks opaque areas — thins the strokes of text and details. 15 Feather Edges PNG Blurs only the alpha channel: hard cutout edges become soft and gradual, colors stay untouched. 16 Clean Edges PNG (defringe) Replaces edge-halo colors of semi-transparent pixels with the nearest fully opaque color. Alpha stays as is. 17 Harden edges PNG Binarizes the alpha channel by threshold: semi-transparent pixels become either fully transparent or fully opaque. 18 Despeckle PNG Opening: removes lone semi-transparent pixels and small specks. 19 Close holes PNG Closing: fills lone transparent dots inside the object. 20
COLOR 25 TOOLS
Two colors PNG Recolors the image into two chosen colors by luminance threshold. 01 Gamma correction PNG Corrects midtone brightness. <1 darker, >1 lighter, 1 — unchanged. 02 Temperature PNG Positive values make the image warmer (more orange), negative ones cooler (more blue). 03 Tint PNG Multiplies color channels by the chosen tint with the given strength. 04 Quantize PNG Reduces the image to k colors via median-cut palette. Transparent pixels are preserved. 05 Custom Palette PNG Maps every pixel to the nearest color from your comma-separated hex list. 06 Dithering PNG Applies Floyd–Steinberg error diffusion or ordered Bayer dithering while reducing to k colors. 07 Grayscale PNG Converts the image to shades of gray using the BT.601 luminance formula. Alpha is preserved. 08 Invert colors PNG Inverts each color channel (255 − value). Alpha is unchanged. 09 Brightness & contrast PNG Adjusts brightness and contrast in the range from −100 to +100. Zero means no change. 10 Change PNG opacity Multiplies the alpha channel by a percentage: 0% — fully transparent, 100% — unchanged. 11 Sepia effect Tints the image into the warm brown tones of classic sepia. 12 Change hue PNG Shifts the hue around the circle. Saturation and lightness are preserved. 13 Extract channel PNG Keeps only the chosen channel — red, green or blue — as shades of gray. 14 Swap channels PNG Swaps two color channels — a quick way to get unusual coloring. 15 Black & white threshold PNG Hard binarization by luminance: every pixel becomes black or white. 16 Posterize PNG Reduces the number of levels per channel — a poster effect. 17 Auto contrast PNG Stretches each channel's range across the full available brightness range. 18 Decrease Color Count PNG Median-cut engine as a quick way to drop to 2–256 colors. Presets marked (extreme/strong/balanced/light) match the classic compression levels. 19 Split PNG into HSL Decomposes the image into Hue, Saturation and Lightness components. 20 Split PNG into HSV Decomposes the image into Hue, Saturation and Value (brightness) components. 21 Split PNG into HSI Decomposes the image into Hue, Saturation and Intensity components. 22 Convert PNG to CMYK Colors Decomposes the image into print-style Cyan, Magenta, Yellow and Key (black) components. 23 Convert PNG to YCbCr Colors Decomposes the image into Luma (Y) and Blue-difference / Red-difference chroma components. 24 Convert PNG to LAB Colors Decomposes the image into perceptual Lightness and green–magenta / blue–yellow opponents. 25
GEOMETRY 18 TOOLS
Add border to PNG Draws a colored frame of the chosen thickness around the image. 01 Fit PNG onto background Places the image centered on a canvas of the given size with a transparent or colored background. 02 Change Canvas Size PNG Sets the exact canvas size: overflow is cropped, missing space is filled with transparency. Anchor picks which part of the image stays. 03 Resize PNG Scales the image with bilinear interpolation. With aspect kept, one side defines the scale; if both are set, the image fits inside them. 04 Crop PNG Cuts out a rectangular area. Coordinates and sizes may go beyond the image — the area is clipped to the intersection. 05 Rotate PNG Rotates by 90°, 180° or 270° clockwise without quality loss. 06 Flip PNG Mirrors horizontally or vertically without quality loss. 07 Add padding to PNG Expands the canvas on all sides by the chosen number of pixels. 08 Tile PNG Repeats the image in a grid of the chosen columns and rows. 09 Center PNG by content Finds the opaque part of the image and centers it on the original canvas. 10 Skew PNG Shifts content horizontally and vertically — a perspective effect. 11 Rotate by custom angle Rotation by any angle. The canvas grows to fit the new bounds; corners stay transparent. 12 Zoom PNG Magnifies content toward the center. The canvas keeps its size — edges are cropped. 13 Trim Empty Space PNG Crops transparent borders around the content. Pixels with alpha above the threshold count as content. 14 Change Aspect Ratio PNG Fits the image into a target aspect ratio: crop the center to fill, or pad with transparency. 15 Swap Orientation PNG Rotates the image by 90° when its orientation differs from the target — landscape becomes portrait and back. Square images are untouched. 16 Symmetric Copy PNG Doubles the canvas by mirroring the kept side onto the empty half — instant symmetric pattern. 17 Shift PNG Moves content by the given X and Y offset. 18
FILTERS 08 TOOLS
Vignette PNG Smoothly darkens the edges of the image, leaving the center untouched. 01 Pixelate PNG Averages every blockSize×blockSize area into one color — classic mosaic. 02 Randomize Pixels PNG Shuffles blocks of the image between positions. Same seed gives the same arrangement. 03 Add Noise to PNG Adds film-grain style noise. Deterministic by seed; monochrome keeps original hue balance. 04 JPEG artifacts Simulates low-quality JPEG re-compression — visible blocks and smeared colors. 05 Blur PNG Gaussian blur: three passes of separable box blur — fast at any radius. Transparent edges do not darken. 06 Sharpen PNG Emphasizes edges with a sharpening kernel; strength sets the blend with the original. 0% means no change. 07 Silhouette PNG Turns all visible pixels into a single solid color while keeping their transparency — instant silhouette. 08
TEXT 03 TOOLS
Add text to PNG Draws a text label on the image: font, size, color, bold, position on a 3×3 grid and an optional backing plate. 01 Date stamp PNG Stamps the current date and time using a format string (YYYY MM DD hh mm ss tokens). Same styling options as Add text. 02 Watermark Tile PNG Covers the image with a repeating diagonal semi-transparent text tile — a protection watermark. 03
ANALYZE 12 TOOLS
Extract Color from PNG Keeps only pixels close to the chosen color and makes everything else transparent — the inverse of Remove Color. 01 Show Transparent Areas PNG Highlights every transparent or semi-transparent pixel with the chosen color so gaps become obvious. 02 Show Grayscale Pixels PNG Finds pixels whose channels are nearly equal and renders them as a mask. Tolerance is in channel units. 03 Show Color Pixels PNG Finds colored (non-gray) pixels beyond the channel tolerance and renders them as a mask. 04 Light Pixel Mask PNG Selects pixels brighter than the luminance threshold. 05 Dark Pixel Mask PNG Selects pixels darker than the luminance threshold. 06 Unique Color Mask PNG Selects colors that occur no more than the given number of times — rare and one-off pixels. 07 Verify If Image Is a PNG Checks the signature of pasted base64 / data-uri content and reports whether it is a real PNG. 08 Check: is PNG grayscale? Reports whether the image consists only of shades of gray. 09 PNG File Size Encodes the image as PNG and reports the resulting file size. 10 Check: is PNG transparent? Reports whether the image contains transparent or semi-transparent pixels. 11 PNG orientation Reports whether it is portrait, landscape or square. 12
GENERATE 21 TOOLS
Create empty PNG Creates a blank canvas of the chosen dimensions, either transparent or filled with a solid color. 01 Create solid color PNG Generates a rectangle of the given size and color. 02 Create random noise PNG Generates an image with random pixels. The seed fixes the result: one seed — one image. 03 Create gradient PNG Generates a smooth transition between two colors along a chosen angle. 04 Color Spectrum PNG Full hue rainbow 0–360° along the chosen axis with adjustable saturation and lightness. 05 Random Color Blocks PNG Fills the canvas with random vivid color blocks. Deterministic by seed. 06 Draw Grid PNG Draws a grid with custom columns, rows and line width on a transparent or white background. 07 Create Placeholder PNG Generates a placeholder rectangle with its dimensions printed in the center. 08 Blend Two Colors PNG A continuous horizontal gradient between two colors. 09 Color Steps PNG A discrete set of evenly spaced steps between two colors. 10 Emoji to PNG Renders an emoji or any Unicode symbol as a transparent PNG of the chosen size. 11 Color Wheel PNG Generates an HSL color wheel: hue around the circle, saturation from center to edge, chosen lightness. 12 Complementary Palette PNG Two opposite colors on the color wheel — the base and its complement. 13 Triadic Palette PNG Three colors evenly spaced 120° apart on the color wheel. 14 Tetradic Palette PNG Four colors in two complementary pairs, 90° apart on the wheel. 15 Analogous Palette PNG Neighboring hues around the base color — calm, related color scheme. 16 Monochromatic Palette PNG Tones of a single hue: lightness varies within the chosen range, hue and saturation stay fixed. 17 Shade Ramp PNG A ramp of the base color getting darker step by step. 18 Mix Colors PNG Averages the selected colors into one swatch. Colors become one uniform fill. 19 Sort Colors PNG Renders the chosen colors as swatches sorted by hue, brightness or saturation. 20 Text to PNG Creates a PNG image from text: the canvas is sized to fit the label plus padding. 21
