Image Resizer — Resize JPG, PNG & WebP
Set an exact width and height, scale by percentage, or fit inside a longest edge. Or use Fit inside an exact frame to reach a size like 1080×1920 without stretching — the whole image is kept and the space around it is filled with a blurred copy, a solid colour, or cropped if you prefer. Convert the format and process a whole batch at once.

Three quick steps
1 · Add
Drop one image or a whole batch. Each is verified by file signature.
2 · Set the size
Pick exact pixels, a percentage, or a maximum edge. Keep the ratio locked to avoid stretching.
3 · Download
Save each result, or take everything as a ZIP. Your originals are never modified.
About resizing
Do you upload my images?
No. Resizing happens in your browser on a local canvas. Nothing is sent to a server.
Will it stretch my photo?
Only in Exact width & height mode with “Lock aspect ratio” switched off. To reach an exact size like 1080×1920 without stretching, use the Fit inside an exact frame mode instead: the whole image is kept and the leftover space is filled with a blurred copy of it, a solid colour, or cropped.
Can I fit a whole batch into a 9:16 vertical frame?
Yes. Fit mode applies to every image in the batch, so a folder of mixed landscape and portrait photos all come out at the same frame size with nothing cut off. Take them together as a ZIP.
Can I enlarge an image?
Percentage and exact modes can scale up, but a browser cannot invent detail, so expect softness. “Fit within longest edge” never enlarges.
Which format should I pick?
Keep original if you are unsure. JPEG suits photos, PNG preserves transparency, and WebP gives the smallest files.
Is there a size limit?
Each file can be up to 60 MB, and output is capped at 6000 px on the longest edge to protect memory on phones.
Good situations for this tool
- A form specifies exact pixel dimensions for an upload.
- Photos from your phone are far larger than a website needs.
- You need a consistent size across a set of images.
- A print or display job requires a specific aspect ratio.
