Convert, compress and inspect — nothing gets uploaded

Images, SVG, PDF, JSON, CSV and text. Every tool runs inside your browser: the files never leave your computer, and there are no size limits and no queues.

Images

Convert imagesPNG, JPG, WebP and AVIF in any direction, in batches. Compress imagesCut the weight by quality, or down to a size you pick. Resize imagesWidth and height with fit control, and no upscaling by default. Crop imagesDraw the crop on the picture and apply it to the whole batch. Rotate and flipQuarter turns, and horizontal or vertical flips. Strip metadataRemoves EXIF, GPS and profiles by re-encoding to the same format. Watermark imagesText on top, in a corner or tiled across the whole photo. View the metadataCamera, exposure, dates and the GPS coordinates if there are any. Favicon generatorOne image into the whole icon set, with the .ico and the HTML snippet. Images to animated GIFA GIF from a sequence of images, in the order you leave them.

Why in the browser and not on a server

Most online converters work the same way: you upload the file, a server processes it, and you download it again. That means waiting for the upload, trusting whoever holds the file, and living with whatever size limit the service imposes.

None of that happens here. The browser already knows how to decode and encode PNG, JPEG and WebP, and the rest arrives as libraries loaded into the page. The file goes nowhere: it is opened, processed and saved from the same tab. You can even pull the network cable once the tool has loaded.
