A free image toolkit that has been online since 2015 and runs entirely on your device. Resize up to 12 images at once in pixels, inches, centimetres, millimetres or percent. Compress a whole batch to an exact target, such as 50 KB or 2 MB, for forms that reject anything larger. Make passport and visa photos with 93 official country templates, face detection and background removal, then lay them out on a print sheet. No upload, no account, no watermark.
Hi everyone. I am John, the solo maker of IMResizer.
I put this online in 2015 and I still run it alone. It is a free set of image tools that work inside your browser. Your files are never uploaded to a server.
Three things people keep coming back for:
1. Bulk resizing in the unit you actually think in. Drop in up to 12 images and set one width and height in pixels, inches, centimetres, millimetres or percent. Pixels for a web upload, millimetres for print, inches for a document.
2. Bulk compression to an exact file size. Government portals, university forms and job applications keep demanding "under 50 kilobytes" or "maximum 200 kilobytes". You type the number, and every image in the queue comes out under it. You can also set dimensions and a size limit together in one step, or pad a file that is too small to be accepted.
3. A passport and visa photo maker. 93 official country templates, face detection that places the head at the required height, and background removal for the plain backdrop the rules ask for. The layout generator then packs copies onto a 4R, 5R, A4 or Letter sheet, so any local print shop can run it cheaply.
There is no server doing the work, which is the whole point. It also keeps the tool usable on a slow connection and on an inexpensive phone. Most of the people who use it are in India and Bangladesh, and that shaped nearly every decision I made.
Tell me where it falls short. Two things I would most like to hear: a file size rule or a country specification that the tool gets wrong, and how it behaves on your oldest phone.
