Image Resizer
Resize up to 10 images at once. Enlarging a photo adds no extra detail. Resizing runs in your browser, nothing is sent to a server.
Resize accepts up to 10 images in one batch, 20MB each, unlike the single-image tools. Enter a width and height in pixels, or pick one of five presets: 1920x1080, 1280x720, 1080x1080, 800x600 and 640x480, for common screen and thumbnail sizes.

How to use
- Add files Drop up to 10 photos into the tool.
- Set dimensions Enter a width or height, or pick a preset.
- Download Save the resized JPG files.
The Keep ratio lock
Turn on Keep ratio and leave one field empty, and Resize fills it in automatically from the other dimension, so your photo never stretches or squashes. Turn the lock off when you need an exact width and height regardless of the original proportions.
Enlarging does not add detail
You can type in dimensions larger than the original photo, and Resize will produce that larger file. It will not look sharper for it, since stretching pixels does not create new detail. Run the photo through Enhance first if you need a bigger photo that still looks sharp, then resize the result afterward if you need an exact size.
Output and where it runs
Resize always saves as JPG. Any transparent area in your source becomes solid white in the output, the same behavior as Crop and Enhance. All the resizing work happens in your browser using your device's own processing, so the batch of photos you resize is never sent anywhere.
When the presets are enough
The five presets, 1920x1080, 1280x720, 1080x1080, 800x600 and 640x480, cover most screen, thumbnail and listing sizes without any manual typing. Use a preset when you just need a standard size fast, and switch to manual width and height only when a specific destination asks for dimensions none of the five presets match.

Every photo you resize stays on your device, none of them are copied to a server.
FAQ
How many photos can I resize at once?
Up to 10 photos in a single batch, each up to 20MB.
What does the Keep ratio lock do?
With the lock on, leaving one of width or height empty fills it in automatically to match the original proportions.
Will enlarging a small photo make it sharper?
No. Enlarging changes the dimensions but adds no new detail. Run the photo through Enhance first if you need a sharper upscale.
What format does Resize save to?
Every result saves as JPG, so a transparent source image shows solid white where it used to be transparent.
