Is this photo resizer really free?
Yes. There is no account, no limit on how many photos you resize, and no mark of ours on your photos. It is made by Capturely, a client gallery service for photographers, and costs nothing to use.
Are my photos uploaded anywhere?
No. The photos are resized by your own browser, on your device. They are never sent to a server, and they are gone when you close the page. Only your last settings (size, fit or crop, quality) are remembered on this device.
Does resizing reduce quality?
A smaller photo has fewer pixels, so it holds less detail than the original; that is what makes it lighter. The tool scales down in steps to keep edges clean and saves JPEG at the quality you set (88 unless you change it). It never makes a photo larger: one that is already smaller than the size you chose keeps its own pixels. Your original file is not changed, and camera details such as EXIF data are not copied into the new one.
What is the difference between fit and crop?
Fit keeps the whole photo and makes it as large as goes inside the frame, so one side may come out shorter than the frame. Crop to fill cuts away what does not fit, so the result is exactly the frame's size, and you choose whether the top, the center or the bottom is kept.
Can I resize many photos at once?
Yes. Add as many photos as you like, choose the size once, and each is resized in turn. Download them one by one or all together as a ZIP file. Large camera files take a few seconds each.
Does it work on a phone?
Yes, in Safari on iPhone and Chrome on Android. On iPhone, Download saves to the Files app; to keep a photo in Photos, tap Save or share, then Save Image. Photos chosen from the iPhone library arrive as JPEG. A HEIC file opens in Safari; another browser may not be able to read it, and the tool tells you when that happens.
