ADVERT
Image Compressor
Compress images in your browser to reduce file size without losing quality. Supports JPG, PNG, and WebP.
How to use this tool
- Add single images or whole folders to the queue.
- Choose output format, quality, and max dimension settings, then run batch compression.
- Download one processed file or export the full batch as a ZIP.
Batch optimization
- Folder uploads let you process large screenshot or photo sets in one run.
- ZIP export keeps original subfolder paths where available.
- Per-file failures are isolated so one bad file does not stop the full batch.
Compression strategy
- JPEG and WebP usually produce smaller files for photos.
- PNG is useful for graphics and transparency when lossless output matters.
- Reducing longest-edge size often cuts file size more than quality changes alone.
FAQ
- Is processing private?
- Yes. Compression and ZIP creation run locally in your browser and files are not uploaded.
- Can I compress a full folder of images?
- Yes. Use folder upload to queue directory contents and export compressed output as one ZIP.
- Why is quality disabled for PNG?
- PNG export in this flow is lossless, so the quality slider does not apply.
