How to use the image resizer
Presentations, blogs, online shop listings and application forms often require photos of a certain size. This tool lets you set the size in pixels or scale by percentage, with presets for common uses. Your photos are processed inside your browser and never uploaded to a server.
Three ways to set the size
- Fit within a maximum size: set width and height limits and the photo is shrunk to fit inside them while keeping its proportions. This is the most common choice.
- Scale by percentage: change the size relative to the original, such as 50 percent. Handy for shrinking many photos by the same amount.
- Set an exact size: forces the photo to the width and height you enter. If the ratio differs the photo is distorted, so use it only when a size is strictly required.
Recommended sizes by use
A blog photo 800 to 1200 pixels wide looks sharp on most screens. Anything larger just adds weight and slows the page. On Instagram, 1080×1350 is the portrait standard and 1080×1080 the square standard.
Printing needs both a print size and a resolution. To print A4 (210×297 mm) at 300 dpi you need about 2480×3508 pixels. To check print quality first, use the Print Resolution Calculator alongside this tool.
Many photos at once
You can process up to 20 photos with the same settings and download the results as one ZIP. Saved file names include the new size, for example photo-1200x800.jpg, so they stay distinct from the originals. When shrinking, the image is reduced in several steps rather than one jump, which reduces jagged edges.
Enlarging a photo beyond its original size adds no new detail and makes it blurry. If you need a larger image, start from the biggest original you have.
Frequently asked questions
Can I set only the width and keep the proportions?+
Yes. In Fit within a maximum size, enter only the width and leave the height at 0. The height is calculated automatically.
Does resizing also reduce file size?+
Usually by a lot. Halving the width and height leaves a quarter of the pixels, and the file shrinks accordingly. If you need to hit an exact file size, use the Image Compressor.
Does enlarging a small photo make it sharper?+
No. Enlarging cannot create detail that was never there, so the photo looks blurry. That is why sizes larger than the original are not applied by default.
Are my photos uploaded to a server?+
No. Everything is processed inside your browser and your photos are not sent anywhere.
Is location data removed when I resize?+
By default camera info and location are removed. Turning on Keep EXIF carries the info over only when saving a JPG as a JPG. If you do not want to expose your location, leave it off.
