Increase Image Resolution — Extend a Small Photo to a Standard Size
Extend a small or low-resolution photo to a standard, consistent size and your target aspect ratio in one step.
Upload a photo and pick a target ratio. The output comes back at a standard, consistent resolution — a real upside for small screenshots, old scans, and thumbnails; not a native 4K or print-DPI upgrade for an already high-resolution photo.

A standard, consistent size — most useful for small or low-res sources
Old scans, phone screenshots, and small thumbnails often fall well short of a usable wallpaper or print size. Every extend on this site outputs a standard, consistent resolution in your target aspect ratio — genuinely a resolution increase when the source was small to begin with. If your source photo is already high-resolution, extending it to a new aspect ratio will not make the file any larger; that's a different job for a dedicated upscaler.
Where increasing image resolution has real limits
This tool fills in detail around what's already there — it does not recover information from a photo that was blurry, heavily compressed, or shot at very low resolution to begin with, and it does not push an already high-resolution photo to native 4K or a print-DPI-verified file. If you need that, pair the result with a dedicated upscaler afterward. Our when-increasing-resolution-cant-fix-a-blurry-photo article walks through that boundary with examples.

Increase image resolution — quick answers
How do I increase image resolution here?
Upload the photo and pick a target ratio — desktop wallpaper, phone wallpaper, or print poster — from the summary chip. Every extend outputs a standard, consistent size, which is a real increase if your source was a small screenshot, old scan, or thumbnail.
What resolution is the output?
A standard, web-ready resolution in your chosen aspect ratio — not a native 4K or print-DPI-verified file. If your source photo is already high-resolution, extending it will not make the file larger; see our honest-limits article for where this tool's ceiling is.
Does increasing image resolution here work on any photo?
It helps most on photos that are small, an old scan, or otherwise low-resolution to start with. It cannot invent detail that was never captured — a very blurry or heavily compressed source photo will not come back sharp, and an already high-resolution photo won't get larger. See our honest-limits article for specifics.
Is increasing image resolution free to try?
Yes. 2 free watermarked previews per device, no sign-up. Sign in afterward for a one-time bonus of 5 free credits, and each finished, unwatermarked photo uses 1 credit.
