Image tools 31

Convert, compress, resize, crop and clean images in your browser. Encoding runs through the jSquash codecs, the same mozjpeg and libwebp encoders desktop tools use. Three of these tools run a machine-learning model on your device: background removal, upscaling and OCR.

Size & format7

n→nConvert imageChange images between JPG, PNG and WebP. Drop as many as you like.n→nCompress imageShrink JPG, PNG and WebP files without uploading them anywhere.n→nResize imageChange image dimensions on your device. Drop as many as you like.n→nCrop imageCut a rectangle out of an image.n→nRotate imageTurn images 90, 180 or 270 degrees. Drop as many as you like.n→nSocial preset resizerCrop-to-fill an image to a named social platform size.n→nID / passport crop presetsCenter-crop a photo to a named ID/passport aspect ratio, then resize to that preset's standard pixel size. This crops and resizes only. It does not check face position, background color, or any country's actual photo requirements.

Edit & effects10

n→nPhoto editor (adjust/filters)Brightness, contrast, saturation and colour filters, on your device. Crop separately with Crop image.n→nAdd border / frameAdd a solid colour border around an image.n→nRounded cornersRound the corners of an image, on your device. Always outputs PNG for the transparency.n→nDrop shadowAdd a soft drop shadow behind an image, on your device. Always outputs PNG for the transparency.n→nDuotone / recolorMap an image onto two colours by luminance.n→nDither imageFloyd-Steinberg dithering to a reduced palette.n→nHalftone imageClassic newsprint-style dot halftone.n→nMeme generatorStamp top/bottom caption text onto an image.n→1Watermark imageStamp one image onto another as a watermark.n→nDocument enhanceClean up a photographed or scanned document: grayscale with contrast stretched to the full range, or a hard black/white threshold for a photocopier look. Operates on an already-captured image file. No camera access.

Build something6

n→1Collage / gridArrange several images into one grid image.n→1Sprite sheet makerPack several images into one sprite sheet with a JSON frame index.n→nApp icon setGenerate a full iOS/Android app icon size set from one square image.n→nOG / social image generatorFit a background image to the 1200x630 Open Graph size and stamp a title on it.n→nPlaceholder generatorA tiny grid-average colour code for image placeholders, on your device. Decode only, not the BlurHash format.n→nExtract colour paletteDominant colours in an image, on your device. Decode only. No image is re-encoded.

Privacy & inspection5

n→nView EXIF dataSee the hidden metadata in a photo, including GPS.n→nRemove image metadataStrip EXIF, GPS and camera data from photos before you share them.n→nPixelate / blur regionMosaic or blur a rectangle of an image: redact a face or a plate.n→1Image diffHighlight the pixels that differ between two same-size images.n→nImage to Base64Turn an image into a data URI you can paste into CSS or HTML.

Runs a model on your device3

n→nRemove image backgroundCut the subject out of a photo and leave the background transparent. The matting model is served from this site and n→nUpscale imageDouble an image's resolution with a super-resolution model rather than a plain resize. The model is served from this site and n→1Image to text (OCR)Read the text out of a scan or photo. The OCR model is served from this site and

Questions

Do my photos get uploaded?

No. Encoding and decoding happen in this tab through the jSquash codecs. The three tools that use a machine-learning model download the model itself from this site, then run it on your device; your image is never part of that request.

Which formats are supported?

JPG, PNG and WebP across the editing and conversion tools. The format is chosen from the file extension, and anything else is refused with "only JPG, PNG and WebP are supported" rather than being guessed at.

Will compressing lose quality?

JPEG and WebP compression is lossy, so yes, by the amount you choose with the quality setting. PNG stays lossless. Each tool shows the size before and after, so you can judge the trade rather than take it on trust.

Does anything here remove EXIF and location data?

Strip EXIF removes the metadata block, and every tool that re-encodes an image drops metadata as a side effect. If a photo needs to be shared without the GPS tag it was taken with, run Strip EXIF and check the result with View EXIF.

Do the AI tools work offline?

Not on first use. Background removal, upscaling and OCR each download a model, so that one run needs a network. Everything else here works offline from the first visit.
