AfterWhere low res images come from, and what to pick
Most small files fall into one of these. Each card says which button turns it into a high res image.
Video and link thumbnails
A saved thumbnail is often only 320 x 180 pixels. 4x gives you 1280 x 720. HD takes it to 1920 x 1080, which is a 6x jump, so the model runs twice; check that result closely.
Screenshots of a photo
A screenshot keeps only the pixels that were on your screen, often a small crop. Pick 2x when you just need it a bit sharper, or HD when it has to fill a slide or a wide post.
Old images saved from the web
Pictures from older websites were often a few hundred pixels wide and heavily compressed. The model is trained to clean up JPEG blocks and noise, so 4x is the natural pick for these small files.
Photos sent through chat apps
Messaging apps often shrink and recompress photos before sending them. Ask the sender for the original first. If that copy is gone, 2x or 4x gives the copy you have more pixels to work with.
Shots from an old phone or camera
Early phone cameras saved files around 640 x 480. 4x gives 2560 x 1920, enough for a full screen or a small print. Faces can come out smoother than they really were.
A small crop of a bigger picture
Cropping one face out of a group shot leaves a low resolution image even if the original was large. Upscale the crop with 4x and compare it with the slider before you use it.
What makes a high res image, and what this tool does
Resolution is a pixel count, not a filter. A low res image has too few pixels for where you want to use it: a 400 pixel wide picture looks fine as an avatar and soft on a laptop screen. On this page, 2x and 4x multiply both sides of your image. HD sets the long edge to 1920 pixels and keeps the shape, with no crop and no bars.
A plain resize only stretches the pixels you already have, so edges blur. Here an AI upscaling model, trained on blurry, noisy and compressed photos, draws sharper edges and cleaner textures at the size you picked. That new detail is the model's best guess, not what the camera recorded, so compare your high res image with the original.
Low res is not the same as low quality. A file can already be large and still look soft, because someone stretched it before. Check the pixel size first: with HD selected, an image whose long edge is already 1920 pixels or more is not processed, while 2x and 4x still multiply it.

- Small online shops
- Family photo keepers
- Video creators
- Anyone with a tiny file
Before you upscale a low resolution image
- Look for a bigger copy first: the original file, an email attachment or a cloud backup usually beats an upscale.
- Check the pixel size, not the file size, so you know whether 2x, 4x or HD gets you where you need to be.
- Export iPhone photos as JPG before you start, because HEIC files are not supported.
- Keep the PNG output for logos or cut-outs with a transparent background, and tick Save as JPG when you need a small file.
- Drag the slider over faces and small text, because skin can turn smoother and tiny letters can change shape.
- Don't expect repairs: scratches, faded color and torn corners stay as they are.
- Download the high res image before you close the tab, since results are not saved anywhere.
