High-quality resampling is applied. Your image never leaves your browser.

Resize images without losing quality

Photos straight from a phone or camera are far too large for the web — they slow down pages, eat storage and often get rejected by upload forms. This free online image resizer shrinks any picture to the exact dimensions you need, in the format you want, with high-quality resampling.

How to use it

Choose an image file, then type the target width and height in pixels. Keep Lock aspect ratio checked (it is on by default) so changing one dimension automatically adjusts the other and the image never looks stretched. Pick an output format — JPEG for photos, PNG for graphics with transparency, WebP for the smallest files — and drag the quality slider for JPEG/WebP. Click Resize Image, check the output dimensions and estimated file size, then Download.

About quality and privacy

The tool uses high-quality bicubic-style resampling (imageSmoothingQuality: high), so downscaled images stay sharp. The size shown is an estimate based on the encoded output. Everything runs locally in your browser — your photos are never uploaded to any server.

Frequently Asked Questions

Is the image resizer free?
Yes, completely free with no sign-up or watermark. Resize and download as many images as you like.
Are my images uploaded anywhere?
No. Resizing happens entirely in your browser using the HTML canvas, so your photos never leave your device.
How do I avoid a stretched image?
Keep “lock aspect ratio” checked. Then, when you change the width, the height adjusts automatically to match the original proportions.
Which format gives the smallest file?
WebP at 80–85% quality usually gives the smallest file with excellent visual quality. JPEG is the safe universal choice for photos.
Why is there no quality slider for PNG?
PNG is a lossless format, so quality does not apply — every pixel is preserved exactly. Use JPEG or WebP when smaller files matter more than perfection.
