Meet a file-size limit
Set a maximum in KB to search for an output at or below your limit. The tool changes quality first. Enable dimension reduction when the destination allows smaller pixels; turn it off for forms with fixed dimensions. Each result reports its actual size and whether the target was met.
Try the 100 KB workflow, or follow the file-size guide for examples and troubleshooting.
Download a whole batch
Choose Download all (ZIP) to save every result at once. Duplicate names receive a numbered suffix. Changing settings does not silently replace a result: use Recompress batch to apply the new settings to the original files.
Smaller images, faster everything
Large image files can slow down pages. This image compressor re-encodes your files in your browser; compare the result because quality and size depend on the original.
Why it’s different
- Private — no uploads, so it’s safe for sensitive or unpublished work.
- Bulk — process up to 20 images and download one ZIP.
- Flexible — compare WebP for efficient compression with JPG for broad compatibility.
Good habits
Keep your original high-resolution files as backups and treat compressed output as your “final delivery” version for the web. For photography, try 80% quality in WebP first, then inspect important details before publishing.
