🗜️ Image Compressor
Compress images in your browser to reduce file size without losing quality. Supports JPG, PNG, and WebP.
Image Compressor
Compress single files or full folders in your browser. Export optimized JPG, PNG, or WebP images individually or as one ZIP.
How to use this tool
- Add individual images or entire folders from your device.
- Set output format, quality, and longest-edge size, then run batch compression.
- Download one result or export all compressed files as a ZIP.
Batch optimization
- Use folder uploads to process many screenshots or photos in one pass.
- Converted files keep original subfolder paths when exported as ZIP.
- Per-file failures are isolated so one bad file does not stop the full batch.
Compression tips
- JPEG and WebP typically produce smaller files for photos.
- PNG is best for graphics with transparency where quality must be lossless.
- Lower longest-edge values and quality settings reduce file size further for web delivery.
FAQ
- Is processing private?
- Yes. Compression and ZIP creation happen locally in your browser. Files are not uploaded.
- Can I compress a full folder of images?
- Yes. Use Add folder to queue all files and export compressed results as a single ZIP.
- Why is quality disabled for PNG?
- PNG export is lossless in this pipeline, so quality controls do not apply.
