Image tools

Build a reorderable workflow from crop, background removal, resize, rotation, compression, conversion, watermarking, colour adjustment, and metadata removal, then run it across images, folders, or ZIP files.

Crop several images freehand or by exact pixels, with common and custom ratios, composition guides, straightening, 90° rotation, flipping, per-image review, and batch export.

Cut images into grids, fixed-size tiles, long-image sections, or manually placed guides for social grids, web captures, print slices, and asset extraction.

Arrange images by drag order and combine them vertically, horizontally, or in a grid with controllable gaps, alignment, and sizing, while previewing the complete composition.

Resize JPG, PNG, WebP, and AVIF images in batches by dimensions, percentage, long or short edge. Fit, crop, pad, prevent enlargement, and create multiple sizes locally in your browser.

Add independent padding around an image without cropping it, choose the image anchor, and export with a transparent or solid-colour canvas.

Create Instagram, Stories, Open Graph, X, and YouTube sizes in one pass, with safe-area guides that help keep important content clear of interface overlays.

Compress JPG, PNG, WebP, and AVIF images in batches with smart optimisation, a target KB limit, or manual quality and dimension controls. WASM encoding runs locally in your browser.

Batch-convert JPEG, PNG, WebP, AVIF, still GIF frames, and HEIC for free, with several formats per image and private local processing.

Convert image files to Data URLs and decode image Data URLs back to files, with a copyable text result and a downloadable image preview.

Rotate, flip, and apply practical tonal adjustments with undo and redo for quick corrections that do not need a layered graphics editor.

Apply text or image watermarks to a batch and control position, size, angle, opacity, outline, shadow, background, and tiled repetition.

Redact faces, number plates, IDs, addresses, QR codes, and screen details locally in batches with rectangles, ellipses, a brush, reviewable face suggestions, solid cover, pixelation, and blur.

Tune exposure, brightness, contrast, saturation, hue, temperature, gamma, sharpness, and blur while using a histogram and same-size comparison to judge the result.

Sample any pixel as HEX, RGB, HSL, and alpha, then extract dominant colours and their shares for design, branding, and visual analysis.

Sample and replace a colour with adjustable tolerance and edge feathering, preserve luminance when needed, or make the selected colour transparent.

Inspect two images with slider, side-by-side, flicker, and single-image views, then calculate changed pixels, change percentage, and mean pixel error.

Inspect dimensions, format, capture details, dates, and GPS metadata, highlight privacy risks, and export a re-encoded copy with metadata removed.

Find exact copies with file hashes and visually similar images with perceptual difference hashes, then recommend a version to keep by resolution and file size.

Turn ordered still images into a GIF with per-frame delays, loop count, colour count, dithering, and compression controls.

Read a GIF timeline and export frames by start, end, and interval while preserving timing information for inspection or reuse.

Edit frame range, order, speed, dimensions, crop, and rotation, then control colour quantisation and dithering for the exported animation.

Reduce GIF size through frame sampling, resizing, palette size, playback speed, dithering, and lossy compression while balancing motion and quality.

Lay out GIF frames as a sprite sheet and export frame coordinates for web animation, game assets, or front-end packaging.
