How the conversion works
Each image is opened, redrawn and saved again by your own browser. Nothing is sent to a server.
- Formats
- Open JPG, PNG, WebP, GIF (first frame), BMP and AVIF, and HEIC where your browser supports it. Save as JPG, PNG or WebP. SVG isn’t supported because it has no fixed pixel size.
- Transparency
- PNG and WebP keep transparent areas. JPG can’t, so they’re filled with the background colour you choose (white unless you change it). This converter keeps transparency but can’t remove an existing background. To remove the background from a photo, you can use our sister site ClearCut. Unlike this converter, it uploads your image to its server to process it.
- Resizing
- Max width, Max height and Fit inside a box keep the shape of the image and never enlarge smaller images unless you allow it. Photos are turned the right way up using their camera orientation.
- Privacy and metadata
- Only the pixels are saved, so location (GPS), camera and other EXIF data are removed from the new files.

Limits
- Up to 50 images at a time, 25 MB each.
- Up to 50 megapixels per image (16.7 megapixels on iPhone and iPad), and 16,384 pixels on the longest side of the result.
- ZIPs over 500 MB ask first, because some devices struggle with them; you can always download the files one by one.
Questions
Are my images uploaded?
No. Every image is converted inside your browser and never leaves your device. The page only fetches its own small ZIP helper when you convert two or more images.
Why does a transparent image get a white background as a JPG?
JPG can’t store transparency, so the see-through areas have to be filled with a colour. White is the default; you can pick black or any colour under Background. Choose PNG or WebP to keep the transparency.
Will it enlarge small images?
Only if you allow it. With Max width, Max height or Fit inside a box, images that are already smaller stay at their size unless you tick “Allow enlarging smaller images”.
What happens to animated GIFs?
The first frame is converted into a still image. JPG, PNG and WebP files made here are not animated.
Can it convert HEIC photos from an iPhone?
Only where your browser can open HEIC itself, which today mostly means Safari. Elsewhere the file is listed as “Your browser can’t open this format.” and the other images still convert.
How is the ZIP named?
biberks-images-YYYY-MM-DD-HHmm.zip, using your local date and time. Files sit at the top of the ZIP, keep their names with the new extension, and duplicates become “photo (2).jpg”. Press Download ZIP to save it.
