Compress image
Compression workflow
Compress image files locally after the composition is already right
Use this page when the job is simply to make one or more image files lighter. Tune quality, aim for a target size, and keep the original frame unless you explicitly decide to resize next.

Compress images locally
Batch compress images without uploading. Adjust quality, set a target size in KB, and download instantly.
Local-only processing. Files stay on your device and are not uploaded.
What happens next
- Select images from your device.
- Adjust settings and preview the result.
- Export locally as JPG/PNG/WebP.
Workflow notes
Default strategy
Start with compression, not resizing
- Keep the current pixel dimensions unless the destination explicitly requires a smaller frame.
- Try format and quality first, then add max width or height only if the file still misses the target.
- Use JPG for photos, PNG for sharp text or transparency, and WebP when file size matters most.
Useful follow-up
Move to the next tool only when the final file still fails the target
Compression solves weight, not canvas size. If the file still needs exact pixels or a different export type, send it to the resizer or converter after this step.
Useful context
Best for
Lighter uploads
Use this when the frame is already right and only the file weight still blocks the workflow.
Good default
80% quality
A practical first pass before you start lowering dimensions or trying target-size tuning.
Target mode
100 KB / 200 KB
Useful for forms, attachments, and systems that reject files over a fixed threshold.
Next step
Resize only if needed
If compression alone is not enough, reduce the pixel dimensions as a second step.
FAQ
Do you upload my images?
No. Compression runs locally in your browser. Your files are not uploaded.
How do I compress images online?
Pick an output format (WebP/JPG), adjust quality, and downscale if needed.
What format is best for photos?
WebP is usually the smallest. JPG/JPEG is the most compatible.
Can I target a specific file size?
Yes (best effort). Use Target size (KB) for WebP/JPG.
Can I batch compress?
Yes. Upload multiple images and download results individually or as a zip.
Why doesn't PNG get much smaller?
PNG is lossless; for photos use WebP/JPG or reduce dimensions.
