About Photo Stretcher
A small set of focused image tools that run in your browser, and a straight account of what they can and can't do.
Photo Stretcher started as one tool for changing an image's pixel dimensions, and it is still built around that. Each tool does one job, with its settings visible and no account needed.
The tools
- Image Stretcher — set an exact width and height, then choose to stretch, resize proportionally, fit with padding or crop to fill. Exports PNG, JPEG or, where your browser can encode it, WebP.
- Resize Image to KB — bring a photo under a file-size limit such as 100 KB, lowering quality first and dimensions only if it has to.
- Aspect Ratio Calculator — simplify a width and height to a ratio, or work out a missing side before you resize.
- Add Padding to Image, Resize Image for Social Media and the Image Converter — add space around a photo, fit it to a platform size, or change its file format.
How they work
Everything runs in your browser using the HTML Canvas API. Images are decoded, previewed and exported on your device and are never uploaded. The site itself is a set of static pages, available in English, Spanish, German and French.
What they don't do
Nothing here uses AI to generate, upscale or extend an image — every pixel in the output comes from the file you provide. Animated images (GIF, animated PNG, animated WebP) and SVG files aren't supported, and there are no user accounts.
Who runs this
Photo Stretcher is built and run by Sabir Ali. It is an independently run site, not a company with a team behind it: one person writes the tools, the guides and this page. You can find him on LinkedIn.
