Your images stay on your device. Nothing is uploaded.
How to resize an image
- Choose or drop your images.
- Enter a width and height in pixels, choose a percentage, or pick a preset. Keep “Lock aspect ratio” on to avoid stretching.
- Select “Resize images” and download the result.
Private by design
Most online image tools upload your pictures to their servers. This one doesn’t: Resize Image runs entirely in your browser, so family photos, IDs, screenshots and client work never leave your device. It’s free, with no watermark and no limit on how many images you process, and you don’t need an account.
Questions
How do I resize without stretching the image?
Keep “Lock aspect ratio” on and fill in just the width or just the height; the other follows. For an exact size in a different shape, choose “Crop to fill” to trim the edges or “Fit with padding” to add borders.
Can I resize many images to the same width?
Yes. Add them all, enter the width and leave the height empty, and each image keeps its own proportions.
Will resizing reduce quality?
Making an image smaller keeps it sharp: it's scaled down in several high-quality steps rather than one. Making it much bigger can't add detail that isn't there, so enlarged images look soft.
What sizes do the presets use?
The sizes each site currently recommends, such as Instagram square 1080 × 1080, portrait 1080 × 1350 and story 1080 × 1920, YouTube thumbnail 1280 × 720, LinkedIn banner 1584 × 396 and X header 1500 × 500.
Are my images uploaded?
No. Every tool runs in your web browser, so your images are read, changed and saved on your own device and never sent to LabAnvil or anyone else. Once the page has loaded, the tools even work offline.
Is it free? Do I need an account?
Free, with no watermark, no daily limit, no account and no cap on file size beyond what your device's memory can handle.
