Image Size Reducer
Shrink the file size of one or more images for free, right in your browser. Process a whole batch at once and download everything as a ZIP β no signup, no upload, no size limit, your files never leave your device.
Large photos and screenshots can quickly eat into an inbox's attachment limit or slow down a web page, but manually resizing dozens of images one at a time is tedious. This compressor handles up to 40 images in a single batch, letting you pick a target dimension and quality once and apply it to everything, then download the results individually or as a single ZIP.

Frequently asked questions
Is this tool free to use?
Yes β completely free, with no signup, no account, and no limit on how many times you can use it.
Is my file uploaded to your servers?
No. Everything runs locally in your browser using your device's own processing power β your file is never uploaded, and we never see it.
How many images can I compress at once?
Up to 40 images in a single batch, each downloaded individually or bundled together into one ZIP file.
What output format do I get?
Every image is exported as a JPG at your chosen quality level, which typically gives the best size reduction for photos and screenshots alike.
Will this work for photos as well as screenshots?
Yes β the compressor works with any standard image file, whether it's a photo, a screenshot, or a scanned document. Photos with lots of detail typically compress best around the Balanced or High quality setting.
