ABOUT THIS TOOL
Simple by design.
Batch-optimize multiple photos. Resize, choose an output format, see per-file sizes, and save a single ZIP without uploading images.
Your input is handled locally in your browser by this tool. Results may vary by device and browser.
Compress and convert several images in one session.
Choose multiple JPEG, PNG or WebP images, set a maximum width and output format, then process the batch. Save individual files or download one ZIP. Keeping the original format avoids replacing an unresized image with a larger recompressed copy.
Does image compression always reduce size?
No. PNG is lossless and some images can become larger. If you select a different output format, compare the before-and-after sizes.
