The Pi7 Bulk Image Resizer is a free tool. It changes the size of many photos at once.
It is part of Pi7, a small set of browser tools for everyday photo and file jobs.
Most online resizers send your files to a server. They resize there and send them back.
That brings limits. A cap on how many photos. A cap on file size. A queue when it is busy. And your photos sit on someone else's disk for a while.
This tool works on your own device instead. It uses the photo tools already built into your browser.
That one choice removes the limits. No upload means no upload cap and no waiting. We never get your photos, so we could not look at them.
Load the page once and it keeps working with the internet turned off.
It does one job. It does not crop, rotate or retouch.
It also cannot read HEIC files from an iPhone. Change those to JPEG first.
For cropping and other single photo edits, use the Pi7 Image Tool.
Nothing. No account, no trial and no watermark. Ads on the page cover the running costs.
Bug reports and ideas are welcome. Plenty of what the tool does now started as a user request.
