Resize a photo without installing anything
Resizing an image by hand with a photo editor means opening a program, finding the right option, and exporting carefully. Image Resizer does the same thing in seconds: upload your photo, enter the width and height you need (or a percentage of the original size), and download the result — no program or extension to install.
All the computation happens inside your own browser — the photo is never sent to any external server. This is useful for client photos, personal documents, or any image you'd rather not upload to the cloud just to resize it.
What is resizing a photo useful for?
It's common to need an exact size for uploading a profile picture, fitting an image to a social network's dimensions, reducing a photo's file size before emailing it, or preparing images with a uniform size for a website or catalog.
Shrinking vs. enlarging
Shrinking a photo has no noticeable quality loss. Enlarging it beyond its original size can look blurry, because there's no more image data to invent — it's a physical limitation of any resizing tool, not just this one.
Frequently asked questions
Is my photo uploaded to a server?
No. The resizing is done using the browser's own drawing functions. Your photo never leaves your device.
Do I lose quality when resizing a photo?
When shrinking, there's practically no noticeable quality loss. When enlarging a photo beyond its original size, the result can look blurry because there's no more image data to work with — this is a physical limitation, not a flaw in the tool.
Can I enlarge a small photo?
Yes, you can scale it up, but keep in mind that enlarging doesn't add new detail: the more you enlarge it, the blurrier it will look.
What formats does it support?
You can upload JPG, PNG, or WebP, and choose whichever of those three you want as the output format (or keep the original). Safari can't export to WebP; in that case the tool lets you know and downloads as PNG instead.
What's the maximum file size?
Up to 25 MB per photo. With very large images the process can take a bit longer, depending on your device's memory.
Do I need to install anything or create an account?
No. It's free, doesn't require sign-up, and there's nothing to install — you use it directly from this page.
Does it work on mobile?
Yes, in any modern browser. On mobile you can choose the photo directly from your gallery.
