AI upscaling, not just stretched pixels
An AI image upscaler estimates edges and textures while adding pixels. It can make small photos more usable at larger sizes, but cannot guarantee recovery of details missing from the original.
Free AI Image Upscaler Online
Upscale low-resolution images with AI for sharper edges, richer textures and clearer details. Enlarge photos 2x or 4x, with output up to 16K.

Upload 1–20 images; multiple images require VIP.
Why use an AI image upscaler?
Choose the enlargement your image needs, then judge the result at its intended size.
02
2x, 4x and resolution presets
Double or quadruple width and height, or choose 2K, 4K, 8K and, with the standard model, 16K. Available choices vary by model; presets are not a promise of a fixed 16:9 crop.
03
A model for the output you need
The standard model offers sizes up to 16K; the fast model offers up to 8K, with an 8192-pixel output limit on either side. Check the available options and credit cost before processing.
04
An online photo enlarger for JPG, PNG and WebP
Upload JPG, PNG or WebP images up to 18 MB each and choose an output format. Upscale a single image, or use VIP batch upscaling to enlarge up to 20 images with the same settings.

Enlarge artwork without changing the brief
Compare fine lines and painted texture in this 2x illustration. Treat the output as a candidate to review, not a guarantee that every brushstroke is unchanged.
What do you need a larger image for?
The right target depends on where the picture will be used, not on choosing the biggest number.
Photo prints and posters
Enlarge a photo for framing, a photo book or a poster. Get the printer's required pixel dimensions first and check a proof before ordering a large print.
4K wallpapers and presentations
Upscale a small wallpaper for a larger display. Match the screen's aspect ratio separately; adding pixels does not extend the image or turn a portrait into a wide background.
Product listing photos
Make a small product photo large enough for a store gallery or closer viewing. Inspect labels, logos and material texture against the real product before publishing.
Family photos and old scans
Prepare a small family portrait or a cropped scan for display. Scan the original at a higher resolution when possible; repair scratches before enlarging.
Illustrations, anime and AI artwork
Upscale artwork for a portfolio or print. Start with a modest enlargement and compare linework and brush texture so added detail does not change the intended style.
Compressed photos from messages
Work with a small shared photo when the original is unavailable. Ask for the original file first: enlarging a compressed copy cannot recreate every lost detail.
2x, 4x or 4K: which size should you choose?
Check the source width and height before choosing a target. More pixels and more faithful detail are not the same thing.
- 2x: double each side
- A 1200 × 800 photo becomes 2400 × 1600. That is four times as many pixels. Start here when you need a moderate enlargement.
- 4x: quadruple each side
- A 1200 × 800 photo becomes 4800 × 3200, with sixteen times as many pixels. Inspect the result closely; a larger multiplier can also make artifacts more visible.
- 1080p to 4K
- A 1920 × 1080 image reaches 3840 × 2160 at 2x, not 4x. This example assumes a 16:9 source. Other aspect ratios need different dimensions.
- Printing at 300 PPI
- For an 8 × 10 inch print at 300 PPI, aim for 2400 × 3000 pixels. Ask your printer about size, viewing distance and cropping; changing DPI metadata alone adds no detail.
Finish edits and cropping first, enlarge once, and inspect the downloaded dimensions. Choose a smaller target if the result looks artificial.
How to get a useful enlargement
A better source and a careful final check usually matter more than the maximum resolution.
Use the original file
Avoid repeated screenshots and message-app copies. Keep your original, and make the final crop before upscaling with the image cropper.
Treat blur before adding pixels
A small image and a blurred image are different problems. For missed focus or camera shake, try to unblur the photo first, check it, then enlarge only as needed.
Check text, logos and faces
AI may invent plausible detail. Compare names, numbers and faces with the original; use text image enhancement for a text-focused task, and still verify every important character. Prefer vector originals for logos.
Check credits and privacy before uploading
Free credits are a limited allowance, not unlimited free upscaling. Review plans and credits and the image privacy policy before uploading sensitive photos.
Prepare the photo, then upscale
Use another tool only when the source needs it. Finish content changes and repairs before your final enlargement, then choose the size for your print or screen.
Edit the image before enlarging
Remove a distraction or change the composition in the photo editor first. Review the edit, then bring the finished image here to increase its resolution for the final use.
Edit a photo before upscaling
Fix a blurry photo before upscaling
If the source is out of focus rather than simply too small, start with the unblur tool. Check edges and facial features before adding pixels so an enlargement does not merely magnify blur.

Restore an old photo before printing
Scratches, creases and fading need repair, not just a larger file. Restore the scan first, inspect the repaired details, then upscale for the intended print size.
Restore a photo before enlargingImage upscaling questions
How do I upscale an image online?
Upload a JPG, PNG or WebP image, then choose a model, 2x or 4x enlargement or an available resolution preset, and an output format. Check the credit cost and confirm to start. Compare the result before downloading.
Can I upscale multiple images at once?
Yes. VIP members can batch upscale up to 20 images; non-VIP users can upload one image at a time. Upload your photos, choose a model, output size and format, then confirm to process the batch with the same settings. Credits are calculated per image, and the total is shown before you start.
Can I enlarge an image without losing quality?
AI can reduce the soft or blocky look of simple enlargement, but completely lossless detail recovery is not guaranteed. Results depend on the original, and generated details may differ. Keep the original and compare at 100%.
Is the AI image upscaler free?
You can try it with available free credits. Each job uses the credits shown for its settings; larger sizes can cost more. Free allowance, account requirements and paid access follow the current tool and pricing information.
Should I choose 2x, 4x, 8K or 16K?
Choose the smallest output that meets your needs. Both models offer 2x and 4x options; the fast model has an 8K output limit, while the standard model also offers 16K. A 16K file is not automatically more accurate or better for printing.
How do I increase image resolution for printing?
Start with the print size and your printer's requested PPI. Multiply inches by PPI to find the required pixels: 8 × 10 inches at 300 PPI needs 2400 × 3000 pixels. Upscale if necessary, check the crop and ask for a print proof.
Does changing a photo to 300 DPI improve its quality?
Changing only the DPI or PPI metadata does not add pixels or recover details. Upscaling changes pixel dimensions; print settings determine how densely those pixels are placed on paper. This tool does not replace print layout or color proofing.
Can I upscale anime or AI-generated artwork?
Yes, you can submit these as supported image files. Start with 2x and compare fine lines, faces and brush texture. If the model changes the style, use a smaller enlargement or return to a higher-resolution original.
Will upscaling fix unreadable text or a badly blurred face?
Not reliably. A sharp-looking character or facial feature can be an AI estimate rather than recovered information. Use the original document or a clearer photo whenever accuracy matters; do not treat an enlarged image as proof of missing detail.
Which formats and file sizes are supported?
This page accepts JPG, PNG and WebP images up to 18 MB each and offers those three output formats. Resolution choices and output limits depend on the selected model.
Can I upscale a photo on my phone without installing an app?
Yes. Open this page in a supported mobile browser, upload a photo from your phone, then choose the output settings and confirm to start. Use a stable connection for large files and download the finished image rather than taking a screenshot of the preview.
