Image Converter — batch-convert photos to JPG, PNG or WebP and resize them

No. Reading and re-encoding happen entirely in a worker thread inside this browser, and your photos are never sent anywhere. Once the page has loaded you can even go offline. The only download while converting is the HEIC decoder, fetched once, and the browser remembers only the last tab you opened and settings such as format and quality. Site-wide visit stats (page address and time on page) are counted anonymously, but they never include your photos or file names.

HEIC is the iPhone's default photo format, but the Windows Photos app and many websites can't open it without an extra extension. Put the photos in the "HEIC to JPG" tab and they become JPGs that open anywhere. To shoot JPG on the iPhone in the first place, choose "Most Compatible" under Settings → Camera → Formats.

For photos, a JPG quality of 80–90 is a safe choice: the difference is hard to see and the file often drops below half its original size. Screenshots full of text and crisp graphics like logos look cleaner as PNG. WebP is usually 25–35% smaller than JPG at the same quality.

Pick a target in the "Compress to Size" tab. It finds the highest quality that stays under the target and, if lowering quality isn't enough, trims the resolution a little at a time. Handy for ID photos and document uploads with size limits. Photos already under the target are left as they are, since re-compressing would only cost quality.

No. Each photo is drawn onto a canvas and saved fresh, so EXIF data such as the capture date, camera model and location (GPS) is not included. That also makes it a handy way to strip your location before sharing a photo. Rotation is applied to the image before saving, so pictures won't end up sideways.

Up to 200 at once. The real limit is your device's memory, so running many 48-megapixel photos on a phone may slow down or stall — shrink the long edge or add them in smaller batches. Safari on iPhone and iPad scales any photo over about 16 megapixels down to fit (a browser limit).

Safari can display WebP images but can't create them. Chrome, Edge, Firefox and Samsung Internet can save WebP. Converting WebP to JPG or PNG works in Safari too.
