Image Resizer
Change the size of photos and graphics to exact pixel dimensions or a percentage. Keep the proportions, or set both sides for a fixed size, and resize many images at once. Nothing leaves your device.
Results appear here. Files are processed on your device and never uploaded.
How it works
- Add imagesDrop one or many. The first image fills in its current size as a starting point.
- Choose the sizeType a width or height with "Keep ratio" on, turn it off to force exact dimensions, or scale by percent. Presets cover common social sizes.
- Pick the formatKeep the original format or convert to JPG, PNG or WebP while resizing.
- DownloadSave each image or all of them as a ZIP.
Pixels, aspect ratio and quality
An image's size in pixels is its width and height, for example 4032 Ã 3024 for a typical phone photo. The aspect ratio is the relationship between the two (4:3 here). With "Keep ratio" on, you set one side and the other follows, so nothing looks stretched. Turn it off only when a form or platform needs an exact size such as 600 Ã 600; if the proportions differ, the picture will be squashed, so crop it first with Crop Image to avoid distortion.
Making an image smaller is always safe and usually makes the file much lighter. Making it larger cannot add detail that was never captured, so upscaled photos look soft. Resizing uses your browser's high-quality smoothing, which gives clean results for photos and graphics.
Common sizes
- Instagram: 1080 Ã 1080 (square), 1080 Ã 1350 (portrait), 1080 Ã 566 (landscape).
- Link previews (Open Graph): 1200 Ã 630.
- Full HD wallpaper or slide: 1920 Ã 1080.
- Email and websites: 1200 to 1600 pixels wide is plenty for most layouts.
If a form limits the file size in kilobytes rather than pixels, resize here and then use Image Compressor, or use the Passport & Visa Photo Maker for ID photos with exact rules.
Frequently asked questions
Are my photos uploaded?
No. Resizing happens in your browser, so even large batches are fast and private.
Why is my resized image blurry?
It was probably enlarged. Enlarging spreads the existing pixels over a bigger area; start from a larger original if you can.
Does resizing remove photo metadata?
Yes. Re-encoding drops EXIF data such as camera details and GPS location, which is good for privacy.
Can I resize HEIC photos from an iPhone?
Convert them first with HEIC to JPG, then resize.
