Privacy and Limitations

Image Compressor is browser-only. The file is decoded and re-encoded with the Canvas API on your device, and neither the original nor the compressed result is uploaded. Files up to 25 MB and roughly 60 megapixels are supported to protect browser memory.

Compression is lossy for JPG and WEBP. For documents or images where quality is critical, use the lossless PNG option or the Image Resizer.

After compressing, host the smaller file with Image to URL to get a direct link you can paste anywhere.

Frequently Asked Questions

Is the Image Compressor free?

Yes, and it has no limits: compression runs locally in your browser with the native canvas encoder, so there are no upload quotas.

Are my images uploaded while compressing?

No. The image is decoded and re-encoded on your device with browser APIs. Nothing is sent to Photo2URL or any other server.

Which formats can I compress?

Any image your browser can decode, including PNG, JPG, GIF, and WEBP. You can output JPG, WEBP, or lossless PNG.

How much can I reduce the file size?

It depends on the source and quality setting. Lower quality settings create smaller JPG/WEBP files, and WEBP is usually the most efficient format for photos and graphics with transparency.

Does compression resize my image?

No. Image Compressor keeps the original pixel dimensions. Use the Image Resizer tool if you also need to change the dimensions.

Will JPG output keep transparency?

No — JPG doesn't support transparency, so transparent areas are filled with white. Choose WEBP output to preserve transparency.
