Batch Image Resizer
Resize multiple images with a bounded queue and individual results.
Choose images or drop a batch
JPG, PNG, WebP and still AVIF. HEIC and SVG use the single-file tools.
25 MiB / 24 MP per image. Queue and completed outputs each limited to 150 MiB.
0 / 0 complete · 0 failed
Cancel stops queued jobs and terminates active workers. On the main-thread fallback, an active encode must finish before cancellation is reported. Retry keeps the original file.
Files stay on your device. Downloads contain only completed outputs.
How this tool works
Choose dimensions and aspect-ratio behavior before starting the queue. Review each output because source shapes differ. Up to 20 supported images run with two concurrent jobs; invalid items fail individually and can be corrected without treating the entire batch as successful.
Choose supported files, review settings, process on your device, and inspect the output before downloading. Conversion may increase file size or change color representation. Re-encoding generally drops original metadata.
The shared queue runs at most two image jobs at once. Invalid items fail individually. HEIC and SVG use single-file tools; ZIP includes only completed outputs.
