What "enhancing" a photo really does
Enhancing a small photo means making it larger and cleaner at the same time. The tool enlarges the picture 2x or 4x, calms the grain, and sharpens the edges so the result does not look soft. It works with what is already in the photo, so a good small photo gets a lot better, and a very blurry one gets only a little better.
Know the limits first
No tool can bring back detail that was never in the picture. If a face is only a few pixels wide, enlarging it will not reveal eyes and skin. The best results come from photos that are small or compressed but still reasonably sharp, such as an old profile picture, a screenshot, or a photo saved from a chat app.
Quick mode or AI mode?
- Quick (recommended). Starts at once and needs no download. It enlarges with smooth scaling, calms noise and sharpens edges without bright halos. It also works on big photos.
- AI (more detail). A small model adds fine detail while it enlarges, so faces, text and edges look cleaner on small photos. The first time it downloads a model of about 8 MB, and your browser keeps it. It is slower, because the model runs on your own device.
AI mode works on a smaller copy of your photo, up to 800 px (Fast) or 1200 px (Detailed) on the longest side, and then enlarges it 2x. On a phone, choose Fast. For a very large photo, Quick keeps more pixels.
How to do it with Velfile
- Open Enhance Photo (HD) and choose your photo. JPG, PNG and WebP up to 50 MB are accepted.
- Under Mode, pick Quick or AI. For AI, also pick the AI photo size.
- Under Enlarge by, pick 2x or 4x.
- Leave Sharpen on Light unless the result looks too soft. Switch on Reduce noise (light) for a grainy photo.
- Choose JPG for a smaller file, or PNG if you plan to edit the photo more.
- Press Enhance. Use Before and After to compare, then press Download.
Your photo is processed in your browser. In AI mode only the model file is downloaded, and your photo is not uploaded to a server.
If the result looks wrong
- Harsh edges or bright halos: set Sharpen to Off or Light.
- AI mode is slow on your phone: choose Fast under AI photo size, or use Quick. You can press Cancel at any time.
- The result is smaller than you asked for: the output is limited to about 30 million pixels so your browser does not run out of memory, and the tool lowers the enlargement and tells you.
After you enhance
A 4x photo can be a large file. If a form limits the size, shrink it with Compress Image. If you need an exact width and height, use Resize Image. For a profile photo or an ID photo with a plain background, try Remove Background or ID Photo (Pas Foto).
