Resize any image to exact pixel dimensions — free, instant, and processed entirely in your browser. Your photos never leave your device.
JPG, PNG, and WebP supported
Job applications and government portals often cap uploads at specific dimensions; marketplaces like eBay and Gumtree prefer around 1600px on the long edge; email signatures work best under 300px wide; and profile photos are commonly 400×400. Websites load much faster when images are resized to the size they're actually displayed at — a 4000px camera photo shown at 800px wastes bandwidth and slows the page.
Keep Lock aspect ratio ticked unless you deliberately want to stretch the image — it keeps the proportions of the original so nothing looks squashed. The tool uses high-quality smoothing when scaling down, which is where most of the visual quality in downsizing comes from.
| Use case | Typical size |
|---|---|
| Profile picture (most platforms) | 400 × 400 px |
| Email signature image | Under 300 px wide |
| Marketplace listing (eBay, Gumtree) | Around 1600 px on the long edge |
| Website images (loading speed) | The size the image actually displays at on the page |
Does resizing reduce image quality?
Scaling down slightly softens fine detail but generally looks excellent with the high-quality smoothing this tool uses. Scaling up cannot add detail that isn't there — enlarged images will look progressively softer the more you enlarge them.
What does lock aspect ratio do?
It keeps width and height in the same proportion as the original, so changing one automatically updates the other. Untick it only if you deliberately want to stretch or squash the image to exact dimensions.
Which output format should I choose?
JPG for photos (smallest files), PNG for graphics, screenshots, or anything needing transparency, and WebP for the best size-to-quality ratio where modern browser support is enough.
Is my photo uploaded to a server?
No. The image is resized on your own device in your browser and never transmitted anywhere — safe for personal photos and documents.
Can I resize to a percentage of the original?
Yes — use the 75%, 50%, or 25% quick buttons, which fill in the exact pixel values for you. You can then fine-tune the numbers before downloading.
What size should a profile picture be?
Most platforms display profile photos around 400×400px and accept a square upload, though they compress it further on their end. Enter 400 in both width and height, or a size the specific platform asks for, then download and upload directly.
How do I make an image file smaller in KB or MB, not just smaller in pixels?
Smaller pixel dimensions usually mean a smaller file, but for the most control over the exact file size at the same dimensions, use our Image Compressor after resizing — it adjusts JPG quality directly to hit a target file size.
Can I download, print or email the resized image?
Yes — click Download to save the resized copy, Print to open it in a print-ready tab (from which you can also choose Save as PDF), or Email to send it via your device's share sheet where supported, or your mail app with a reminder to attach the downloaded file.
