Resize and compress images.

Some combinations cannot be reached with the available quality settings. Try a different accepted format, a higher limit or smaller dimensions if the receiving form permits them. We never silently reduce dimensions you explicitly request.

No. Enter one dimension to preserve the original proportions. Enter both to fit the image inside an exact-size canvas, with padding where needed. Padding is transparent in PNG or WebP and white in JPG.

Use a format accepted by the destination. JPG is often useful for photographs at small file sizes. PNG is lossless and supports transparency, but can produce larger files. WebP also supports transparency. JPG replaces transparent areas with white.

Yes. The tool develops DNG RAW data on your device and can save the result as JPG, PNG or WebP. “Keep original format” saves DNG files as JPG. RAW rendering can look different from the image produced by your camera or editing software, and some DNG variants may not be supported.

No. Opening, resizing and compressing happen in your browser. The tool does not send your image to us. Read the privacy notice.

Yes. Select up to 10 images at once. The same file-size limit, dimensions and output-format setting apply to each one. Results are checked separately, so if one image cannot meet the requirements, you can still download the others. Each image can be up to 100 MiB, 60 megapixels and 16,384 pixels per side. Total batch output is limited to 200 MiB. Very large images need more device memory and may take longer to process.

The tool checks file size, pixel dimensions and format. It cannot check composition, background, subject position, DPI or a particular organisation's photo rules. Animated images are not supported. Always review the result against your destination's requirements.
