FreemiumBeginnerWebiOSAndroid
Overview
Simple Image Resizer changes the size of an image in the browser. You set an exact width and height in pixels, or shrink by a percentage, and it keeps the aspect ratio locked so the photo does not stretch. It can also resize down to a target file size in KB or MB, which is the fix when an upload form rejects a photo for being too large. It reads JPEG, PNG, WEBP, HEIC, BMP and GIF.
It works in any browser, and the same vendor's phone apps are on iOS and Android as Photo & Picture Resizer. Basic resizing is free with no account, up to 3 files in a batch. Files over 15 MB need premium, a subscription you can cancel at any time that also removes ads and raises the batch limit.

When to use
Use Simple Image Resizer when you need to change an image's size without installing anything:
- You need to shrink a photo to fit a website, an email or an upload form, and you want it done in the browser you already have open.
- You have to hit an exact pixel size, so you want to type the width and height yourself rather than accept a preset.
- A form is rejecting your file for being too big. You can resize to a target KB or MB instead of guessing at dimensions.
- You are on a phone and do not want to install an app for a one-off resize. The web version works in a phone browser.
- You work with ordinary formats like JPEG, PNG, WEBP or HEIC and want a smaller copy of the same picture.
When NOT to use
Skip Simple Image Resizer if any of these describe you:
- You want to enlarge a small photo without it going soft. Resizing up here stretches the pixels you already have. An AI image upscaler invents the extra detail instead.
- You have a lot of images to resize at once. The free tier takes 3 files per batch, so a big job means paying or working in rounds.
- Your images are confidential. They are uploaded to the vendor's servers to be resized rather than processed on your own machine.
Frequently asked questions
Yes, the web tool is free and needs no account. The free tier takes 3 files in one batch, and files over 15 MB need premium. Premium is a subscription you can cancel at any time. It removes ads and raises the batch limit: the vendor's pricing page says up to 25 files at once, while a popup on its home page says 10. Ordinary single-image resizing does not need it.
No. It changes the pixel dimensions, so enlarging stretches the existing pixels and the result looks soft. To add real detail when scaling up, use an AI upscaler instead.
Yes. The official mobile app is called Photo & Picture Resizer, not Simple Image Resizer, and it is on both the App Store and Google Play. It is made by the same vendor and resizes, compresses and crops images on your phone.
It works with JPEG, PNG, WEBP, HEIC, BMP and GIF. You upload one of these and download the resized copy.
The vendor states that uploaded files are not shared with third parties, and that a file you have downloaded is removed from the server within a minute. It states anything left is deleted permanently when the download link expires 24 hours later. The images are processed on the vendor's servers rather than on your device.
