Resize multiple images in one private batch
Apply one maximum width, height, format, and quality policy to as many as 20 images. Files are processed sequentially and packaged into a ZIP inside this browser tab.
How it works
Choose 2–20 images
Select JPG, PNG, or WebP files under the per-file and aggregate browser limits.
Set shared bounds
Choose maximum width and height, output format, quality, and whether smaller images may upscale.
Verify and download
Review every measured output and download one locally assembled ZIP with collision-safe names.
What stays private here
- Each source image is decoded and encoded sequentially in this browser tab.
- The finished ZIP is assembled locally and is never uploaded to Peelaway.
- Analytics receive only aggregate counts, dimensions, formats, quality, and byte sizes.
- No filename, directory path, image pixel, object URL, or archive byte reaches analytics.
Questions about this tool
Will every image have exactly the same dimensions?
No. Each image keeps its proportions and fits inside the shared maximum width and height. Portrait and landscape sources can therefore finish at different dimensions.
Does the batch resizer enlarge small images?
Not by default. You can explicitly allow upscaling, but interpolated pixels cannot restore detail that is missing from the source.
What happens to transparent pixels?
PNG and WebP can retain transparency. JPEG cannot, so transparent areas are flattened onto white before encoding.
Are the images or ZIP uploaded?
No. The browser decodes and encodes one image at a time, then assembles the ZIP locally. Peelaway analytics receive only aggregate counts, dimensions, formats, and byte sizes.
