PNG encoding is lossless and does not use quality or size targets. The file may not be smaller.
Advanced settings
Keep the image ratio without enlarging small images. A size target may lower quality; Maximum quality sets the upper limit. PNG does not use quality or size targets.
Small targets may lower quality considerably. Check details, raise the target or remove the limit if needed.
Current output: JPEG. Transparent areas become white. To keep transparency, choose PNG or WebP in Advanced settings.

Results and thumbnails have reached 100 MiB. Download them and clear the queue before starting another batch.
Some results are larger than the originals. For smaller files, lower the quality, choose WebP or set a size target, then select “Clear this task” and add the images again.
How to use this tool
- Add up to 50 images.
- Check the current output format and size settings, then select Start compression. All images in the run use those settings.

- Select Download successful images as ZIP. To reprocess completed images with new settings, save the results you need, clear the queue and add the images again.
A few useful things to know
- Does one failed image stop the batch?
- No. Successful images can be downloaded individually or as a ZIP, and failed items can be retried. Up to 50 files are accepted; processing pauses at 100 MiB of retained results.
- Why did a file get larger?
- Your original may already be optimized. Conversion or re-encoding can increase size. Check the actual change and retry with different settings.
- What is included in the ZIP?
- Only completed results are included, not failed or cancelled items. Results over the size target are labeled; inspect them before use.
- How can I check local processing?
- Prepare offline resources, disconnect, reopen this page and process a sample image without private information. This page loads its tools from ImgDeal and offers optional action statistics.
- Are my images saved on this site?
- Images and editing inputs remain in this tab’s memory. Clear the task or close the tab to release them. Offline caches contain program resources only.
