Frequently Asked Questions
How many images can I resize at once?
Up to 50 images per batch, bounded by your browser memory. Images are processed one at a time to keep memory usage low.
What is the output file naming?
Each output keeps its original name with the new extension, for example photo.webp or photo-1024.jpg, and everything is bundled into one ZIP.
Are batch operations processed on a server?
No. Every image is decoded, resized, and encoded locally on your device. The ZIP archive is also built in your browser.
More Free Browser Image Tools
Every tool runs 100% locally in your browser memory with zero server uploads.
