π‘ How to use the image resizer
Whether you need product photos at a fixed pixel width, a smaller thumbnail for a blog, or a lighter attachment for email, you can resize by exact pixels, by percentage of the original, or with one click using a size preset. Upload several images at once β each one is processed independently and gets its own download button.

01
Pixels vs. percentage β which should you use?
If you need an exact size (e.g., an 860px-wide product image or a 400Γ400px avatar), use pixel mode. If you just need a relative change, like "make it half the size," percentage mode is faster. With aspect ratio locked, entering just a width automatically computes the matching height so images never look stretched or squished.

Best for
JPEG
High compression, adjustable quality
Photos, product images
WebP
Smaller file size at the same visual quality
Faster-loading websites
PNG
Lossless, supports transparency
Logos, icons, screenshots
The quality slider only affects JPEG and WebP output. Around 90% keeps images visually near-identical to the original while shrinking file size significantly.

Tips for batch processing multiple images
Drop or select several images at once and the same size, format, and quality settings will be applied to every one of them. Each result shows its own thumbnail and download button, so you can save just the ones you need. Photos taken in portrait mode on a phone are automatically rotated using their EXIF orientation data before resizing.
No. All resizing happens entirely inside your browser and the image data is never sent anywhere.
How many images can I process at once?
There is no fixed limit on the number of files, but each image must be 30MB or smaller. Processing time depends on your browser and how many files you upload.
How does the height get calculated when the aspect ratio is locked?
With the lock enabled, entering a width (or height) automatically computes the other dimension based on the original image's ratio.
Why does my portrait phone photo look sideways?
Modern browsers read the EXIF orientation tag and rotate the image correctly before resizing. Some older browsers may not apply this automatic rotation.
