Bulk Resize, Compress & Convert — Free & Private
Process a whole batch of images at once and download them individually or as a single .zip. Everything runs locally — nothing is uploaded.
Frequently Asked Questions
Does this upload my images to a server?
No. Every image is processed entirely in your browser using the Canvas API, and the .zip file is also built locally. Nothing is ever uploaded.
How many images can I process at once?
There's no fixed limit — since everything happens locally, the only constraint is your device's available memory. Images are processed a few at a time to keep the browser responsive.
Can I use a different setting for each image?
The bulk tool applies one operation and one set of settings to every image, which covers the common case of processing a batch the same way. For per-image control, use the individual Resize, Compress, or Convert tools.
What does 'leave blank to scale proportionally' mean for resize?
If you only set a width, each image's height is calculated automatically to preserve its own aspect ratio — useful when your images aren't all the same shape. Setting both width and height stretches every image to that exact size.
Is there a bulk API for automations or AI agents?
The Image Tools API processes one image per request. For bulk automation, call it once per file from your own script or agent — see the API docs for details.
