Nothing uploads. Everything stays on this device.
Files convert one at a time on your device, then download as a zip — nothing is uploaded. RAW files are fully decoded before conversion, which can take a moment per photo. Resizing never enlarges a photo past its original pixels. JPEG exports keep your EXIF and copyright (tick the box to drop GPS); PNG and WebP carry no EXIF.
Batch resize and convert photos — including HEIC to JPG
Drop a whole card's worth of photographs and get them back exactly the way you asked: a single format, a single longest-edge size, zipped and ready. Use it to convert HEIC to JPG straight off an iPhone, turn a folder of PNGs into lightweight WebP, or batch resize photos down to a web-friendly 1600 or 2048 pixels before you upload them anywhere.
Everything runs in your browser. Each file is read from your device, resized on a local canvas, re-encoded and collected into a zip — one photo at a time, so even a couple of hundred files stay light on memory. Nothing is uploaded, no account is needed, and no watermark is ever added. JPEG exports keep the camera EXIF and your copyright intact; strip the GPS coordinates with one checkbox if you would rather not share where a shot was taken.
Resizing is honest: the longest-edge sizes only ever make a photograph smaller, never larger, so nothing is upscaled into mush. Pick "Keep original format" and every file stays its own type where the browser can re-encode it — the queue tells you plainly when a source format has to fall back to JPEG. Unsupported or damaged files are marked in the list with the reason and skipped, so one bad frame never stops the batch.
