Resize image
Set exact pixels or scale by percent. Aspect ratio stays locked unless you unlock it.
Scales the longer side down to this, keeping proportions. Smaller images are left alone.
How to use Resize image
- Drop your JPG, PNG, WebP or AVIF files onto the upload area.
- Pick a preset (1080, 1600 or 2048 px) or enter a width and height. Keep proportions stays on unless you turn it off.
- Choose an output format under Save as.
- Click Resize.
- Download each image, or click Download all for a zip.
A photo straight off a modern phone is around 4000 pixels wide. Almost nothing needs that. A full-width web image rarely exceeds 2048 pixels, a profile picture needs a few hundred, and an upload form usually caps out well below either. Resizing before compressing is what actually gets file size down — it removes pixels rather than degrading the ones you keep.
Longest edge mode is the safe default for a mixed batch: it scales anything larger down to your ceiling and leaves smaller images untouched, so nothing gets blown up and blurry. Exact size mode is for when a specification is fixed and you need every output identical.
Resizing runs on the browser's own image pipeline, on your device. Nothing is uploaded, and you can queue up as many files as your memory will hold.
Questions
Will resizing make my image blurry?
Scaling down is safe and often looks sharper after compression. Scaling up is the problem — there is no extra detail to invent, so enlarging always softens the picture. For that you want an upscaler, not a resizer.
What size should I use for the web?
2048 pixels on the longest edge covers full-width hero images on high-density screens. 1080 is plenty for anything shown at normal size in an article.
Can I resize many photos at once?
Yes. Drop in the whole batch, pick your setting once, and download the results as a ZIP.
Are proportions kept?
In longest edge mode, always. In exact size mode you can unlock proportions, but be aware that stretching to a mismatched aspect ratio will visibly distort the picture.
