Resize Image
Enter a width, a height or a percentage and resize one photo or a whole batch to the same size. Everything happens in your browser, and your files never leave your device or reach a server.
Choose photos, enter the size you want and tap Resize.
Fit, fill or stretch: what's the difference?
When you set both width and height and they don't match the photo's aspect ratio, you need to decide how to fit it. Here's a 4:3 photo (4000×3000) resized to 1080×1080:
| Mode | Result | What happens |
|---|---|---|
| Fit inside | 1080×810 | The whole photo is kept and fits inside the box, so one side ends up smaller than requested. |
| Fill and crop | 1080×1080 | Exactly the requested size; the extra left and right edges are cropped from the center. Best for Instagram and profile photos. |
| Stretch | 1080×1080 | Nothing is cropped, but people and objects look squashed or stretched. |
Recommended sizes
- Instagram feed: 1080×1080 square or 1080×1350 portrait (4:5). Larger uploads are scaled down to 1080px wide by the app.
- YouTube thumbnails and desktop wallpapers: 1280×720 or 1920×1080 (16:9).
- Profile photos (LinkedIn, Slack, Gmail, forums): 400×400 is sharp everywhere; most services display them as a circle, so keep the face centered.
- Blog posts and product pages: 800–1200px wide looks crisp on phones and laptops. Anything wider mostly adds file size.
- US passport and visa photos (digital): a square between 600×600 and 1200×1200 pixels, according to the U.S. Department of State. A printed 2×2 inch photo scanned at 300 DPI is exactly 600×600. See the DPI & print size calculator for how pixels relate to print sizes.
Smaller dimensions mean a smaller file, but if a site limits the file size ("under 240KB"), the image compressor lets you set that target directly.
Frequently asked questions
Are my files uploaded?
No. Resizing happens entirely in your browser, and your photos are never sent to or stored on a server. The resized files are saved straight to your device.
Will enlarging a small photo make it sharper?
No. Enlarging fills in new pixels from the surrounding colors, so the image gets bigger but looks softer. If you need more resolution for printing, take or scan the original at a higher resolution.
Do I lose quality when making a photo smaller?
Fine detail is reduced along with the pixel count, but at normal viewing size it's hard to tell. For big reductions the tool halves the size step by step, which avoids jagged edges. JPG and WebP add a little compression loss depending on the quality you choose.
Will portrait photos end up sideways?
No. The tool reads the photo's rotation (EXIF orientation) and turns it upright before resizing, so width and height may appear swapped compared with what the original file reports.
