Image compressor
Compress Images Online — Live Single Preview and Pro Batch Mode
Single-image mode shows a live before/after comparison as you adjust format, quality and size. Generate the full-resolution output only after the preview looks right; Pro adds a separate no-preview batch mode.

FAQ
Are my images uploaded?
No. Selected images are not uploaded to a Dropabit conversion server.
Why can an output be larger?
The result depends on the original compression, format and image content. The workspace flags larger outputs so you can keep the source file.
