Detailed User Guide
Resize and convert many images at once
Apply the same resize, format, and quality settings to an entire folder of images in one pass, instead of editing them one at a time.
Format choice affects size and use
JPG is small and universal, PNG keeps transparency, and WebP offers the best compression for the web. Choose based on where the images will be used.
Quality is the size lever
Lower quality shrinks file size but softens detail. For web use, a moderate quality setting is usually the right balance.
Batch output arrives as a ZIP
Because browsers cannot save many files at once, the results are packed into a single ZIP for easy download.
Processed locally for privacy
All images are handled in your browser, so nothing is uploaded to a server.
Test settings on one image first
Before running a hundred files, apply your chosen resize and quality settings to a single representative image and check the result. A quality level that looks fine on a bright product photo can soften fine text or low-contrast detail in others. Locking in the right settings first saves a full re-run of the batch.
