Images
Compress images, convert formats, add watermarks, slice into grids, crop ID photos, generate barcodes. All on the browser canvas, nothing uploaded.
Tools in this category
Image Converter
Convert between PNG, JPEG, WebP, AVIF, BMP and TIFF, with adjustable quality and size. JPEG output lays a background, so transparency never turns black.
Image Slicer
Slice an image into a grid for nine-tile posts or a tall image. Six grid shapes, per-tile padding, and names padded for posting in order.
Image Watermark
Add a text watermark to a photo: nine positions plus tiling, with the size scaled to the image so it looks the same at any resolution.
ID Photo Crop
Crop a photo to ID sizes — 25×35 mm, 35×49 mm and US, Japanese or Schengen visa specs — at 300 or 600 DPI. Cover-cropped, so faces never stretch.
Barcode Generator
Generate barcodes online in CODE128, EAN-13, CODE39, ITF-14 or UPC-A, and download them as PNG. Format mismatches are explained instead of rejected.
Placeholder Image
Generate a placeholder image of any size with the dimensions written on it, for mockups, prototypes and layout previews. SVG by default, or PNG and JPEG.
Image Compressor
Compress an image to a target size (say under 200 KB): the tool binary-searches for the highest quality that fits. Quality steps and size limits too.
Favicon Generator
Turn one image into a full site icon set: favicon.ico (16/32/48 packed), apple-touch-icon and the 192 and 512 PWA sizes, centre-cropped to square.
Image Stitcher
Stitch images into a tall strip, side by side, or a grid. Adjust the gap, corners and background; uniform sizing never upscales. Runs in your browser.
ID Photo Maker
Make a passport or US visa photo: crop to 2 × 2 in (51 × 51 mm) or another standard ID size, recolour the background, and print a sheet of copies.
Signature Extractor
Turn a photo of a handwritten signature into a transparent PNG. Removes the paper automatically, trims the margins, and can force black or pen-blue ink.
App Icon Generator
Generate the full iOS AppIcon set, Android mipmaps and adaptive icons, and a macOS .icns from one image. Adjustable corners and padding, flattened for iOS.
Image Info
Read everything an image carries: format details, camera settings and where it was taken. GPS is called out separately; the report exports as text or JSON.
Image Rotate
Rotate an image 90°, 180° or mirror it, and fix sideways phone photos by applying the EXIF orientation. Keeps the original format and runs locally.
QR Code Reader
Read a QR code from a screenshot or photo. URLs, WiFi settings, contact cards and plain text are recognised; WiFi passwords are pulled out for you.
Round Corners
Round off an image with a radius in pixels or as a percentage of the short side (50% is fully round). Transparent PNG by default, JPEG with a fill colour.
CSS Sprites
Pack several small icons into one image and get the matching background-position CSS, so the page fetches all of them in one request. @2x supported.
SVG Editor
Write SVG on the left, see it render on the right. Switch backdrops (checkerboard, light, dark) and get checks for xmlns, viewBox and external references.
Font Viewer
Drop a ttf / otf / woff / woff2 to preview it: a size ladder of samples, plus a glyph grid that measures which code points really exist.
Image to SVG
Trace PNG and JPG bitmaps into SVG vector paths, with adjustable colour count and detail. Good for icons and line art; photos give you blobs.
Payment Codes Together
Merge two payment QR codes into one image, side by side or stacked, with optional captions. Both codes keep their original pixels, so scanning still works.
Image Colour Picker
Click any point to read its colour as HEX, RGB and HSL, plus the overall average colour and a palette sorted by share. Radius is adjustable.
Background Colour Remover
Make a colour transparent and export a PNG: adjustable tolerance, connected-area-only flooding, edge feathering and de-fringing.
Image Filters
Apply a photo filter in one click: vintage, faded, negative, X-ray, contrast, cool, warm, greyscale, sepia or custom, with contrast control.
Image Border & Frame
Add a border or frame: plain, double line, polaroid (wider bottom), rounded stroke or drop shadow, with per-side widths and 1x or 2x export.
Code Screenshot
Render code into a PNG with syntax highlighting for several languages, dark, light or high-contrast themes, line numbers, padding and rounded corners.
Image Diff
Compare two images pixel by pixel, set a threshold, ignore anti-aliasing, colour darker and lighter changes, and export a transparent diff image.
Print Test Page
Generate a printer test page: registration marks, gradients, CMYK patches, a grey wedge, hairlines and a millimetre grid, sized exactly by DPI.
Signature Pad
A blank canvas to sign on with a mouse, finger or stylus, exported as a transparent PNG that sits on top of a document.
