Resize one image or a batch of 20, with sharp high-quality resampling.
Resize images to exact pixel dimensions or scale them by percentage — one file or a batch of up to 20 at once. Resampling uses pica's high-quality filters, so downscaled images stay sharp instead of going soft.
Everything runs locally in your browser. Batch results download individually or as a single ZIP.

No. Everything runs locally in your browser using the Canvas and File APIs. Your files are never uploaded to a server, and nothing is stored after you close the page.
Yes. You can add up to 20 images (250 MB total) and resize them in one batch, then download everything as a ZIP.
Downscaling uses high-quality resampling (the pica library's Lanczos-class filters), which preserves detail far better than the browser's default scaling. Enlarging beyond the original size always costs some sharpness — that is true of any resizer.
Yes. Switch to percentage mode to scale images relative to their original size — useful when a batch has mixed dimensions.
No — each image keeps its original format. To change format as well, run the result through the Format converter.
