Photo Size Reducer

Compress Image to 70KB

An odd number for a limit, but the same handful of steps will compress image to 70KB.

JPG, PNG or WebP. Stays on your device.

Seventy kilobytes is not a round number, and you rarely see it in the wild. Whatever the reason a form chose it, you need a file at or under that weight. Here is how to reduce photo size to 70KB from a phone or a computer. Any decent photo compressor can produce a 70KB image, and the steps below show how to reduce image size in KB with this one.

Steps on a phone

  1. Open your gallery, find the photo, and crop it to what the form needs. Leave a small margin.
  2. Come back to this page and tap the upload box. Choose the cropped photo.
  3. Type 70 in the target box and keep the unit on KB.
  4. Tap Compress. It takes a second or two.
  5. Look at the preview. If the size shown is 70 KB or below, tap Download. The file lands in your downloads folder.
  6. Go back to the form and upload that downloaded file.

Steps on a computer

The steps match, with one shortcut. You can drag the picture from a folder straight onto the box instead of clicking. The result downloads like any other file. If your browser asks where to save it, pick a place you can find again, such as the desktop.

What happens inside

The tool tries a range of JPG quality settings and keeps the best one that still fits under your target. That is why the result looks as good as 70 KB allows and no worse. When the picture is huge, it also reduces the width and height by a small fraction each round until it fits. The whole process runs in your browser, so your picture is not uploaded.

Quick fixes if it does not work

  • File still too big: the tool will say so and show the smallest file it reached. Crop more, or use a plainer photo.
  • Looks too rough: aim a bit higher if the form allows, such as 100 KB.
  • Rejected anyway: check whether the form also has a pixel size rule or a file type rule. This page adjusts file weight only.
  • Not sure of the limit: if your form says "under 70 KB", aim for 65 to be safe.

For many pictures at once

If you have a stack of photos to shrink, the Android app handles several in one go and works offline. On this page, do one picture at a time.
