Questions About Bulk Image Resizer
Does it upload my images anywhere?
No. Resizing and format conversion run locally in your browser tab. There is no upload step and no server-side copy of your files — your images never leave your device.
What formats can I convert between?
Bulk Image Resizer supports JPG, PNG, and WebP, and lets you convert between these formats in the same step as resizing, so you don't need a separate conversion tool.
Can I resize a whole folder at once?
Yes. You can upload an entire folder and the extension processes every image in it as a single batch, instead of opening files one at a time.
Are there size presets for social media?
Yes. Bulk Image Resizer includes smart presets for social media and web use, so you can apply a ready-made size across a whole batch instead of looking up pixel dimensions yourself. Custom width and height are also available when you need an exact size a preset doesn't cover.
Does it work without an internet connection?
The actual resizing and conversion run locally in your browser rather than on a remote server, so no file upload or server round-trip is needed to process your images.
Will resizing in bulk reduce image quality?
Bulk Image Resizer is built to maintain image quality while reducing file size, so images stay sharp at the new dimensions rather than looking compressed or blurry.
How many images can I process in one batch?
There's no artificial cap on batch size — select as many files or as large a folder as you need, and the extension works through hundreds of images in seconds since everything runs locally rather than queuing on a server.
Do I need to create an account to use it?
No account or sign-up is required. Install the Chrome extension from the Chrome Web Store and start resizing images right away.
