Image tools

Resize, compress and convert images to an exact specification. Files are processed on your device and never uploaded.

• Image CropperCrop by dragging, by aspect ratio, by exact pixels, by percentage, by auto-trimming blank edges, or split into a grid of tiles.
• Compress Image to Exact KBHit an exact file-size target such as 20KB, 50KB or 100KB without guessing or losing legibility.
• Image Resizer to Exact PixelsResize to an exact width and height, with a choice of fit, fill, or stretch, plus optional format conversion.
• Image Format ConverterConvert HEIC, AVIF, WebP, JPEG, PNG or GIF to JPEG, PNG or WebP, including iPhone HEIC photos, with a quality control for lossy formats.
• Image Metadata RemoverStrip EXIF data from a photo before sharing it, so GPS coordinates, device model and timestamps are not published.
• Print Size CalculatorTurn pixel dimensions into a print size at any PPI, and see which axis limits the fit to a real sheet of paper.
• Image HistogramFour 256-bin histograms with BT.601 luminance, plus a clipping map that shows where highlights actually blow out.
• EXIF ViewerA byte-level EXIF reader with no dependency: camera settings, GPS in degrees, and the thumbnail privacy trap, read on device.
• Favicon GeneratorBuild a multi-size favicon.ico, apple-touch-icon and web app manifest, then read the ICO back as a hex breakdown.
• Social Media Image ResizerSixteen placements with the part of your image that survives each crop, plus Open Graph tags and the YouTube size correction.
• Perceptual Image HashaHash, dHash and pHash with Hamming distance, calibrated so 32 bits apart is coincidence rather than a match.
• Product Photo Spec CheckerCheck one product photo against marketplace pixel, format and background rules, and see exactly what cannot be measured.
• BlurHash & LQIP GeneratorEncode a BlurHash, a ThumbHash that keeps alpha, or a 24px WebP LQIP. Length depends only on the component count.
