What this tool helps you do
- Reduce transfer weight while optionally capping maximum width, without forcing every source image into a new pixel size.

- Use codec, quality, and width controls for marketplace cards, PDP delivery, email attachments, supplier handoffs, and ad-ready source files.
How it works
- 1Add up to 10 JPEG, PNG, WebP, AVIF, or GIF files; duplicate selections are ignored.
- 2Choose the output codec, quality level, and optional maximum width.
- 3Run the batch, inspect every result card, then download one file or the complete ZIP.

Questions about this browser tool
Does compression always reduce image dimensions?
No. Pixel dimensions stay unchanged unless the source is wider than the configured maximum width. The remaining reduction comes from the selected codec and quality setting.
Why can a compressed PNG become larger?
PNG is lossless and may grow after re-encoding. For photographic product images, WebP or AVIF usually provides a smaller result when the destination marketplace supports those formats.
Are my images uploaded to a server?
No. Source files, QR values, GIF frames and PDF pages are processed in this browser with Canvas and local JavaScript libraries. The site does not upload the files or save outputs to account history.
What are the browser limits?
Use a current Chrome, Edge, Safari or Firefox release. Very large images, long GIFs and complex PDFs can be limited by available device memory, and encrypted PDFs may need to be unlocked first.
