Features
2K and 4K output
Increase image resolution to 2K or 4K when you need higher-detail exports for printing, presentation, or display.
Free 200% enhancement
Start with a free 200% upscale to check quality before moving to a higher-resolution export.
Batch uploads
Upload more than one image at a time to process a set of photos, scans, or artwork together.
Multiple export formats
Export finished files as JPG, PNG, or WebP so the result fits your next workflow without extra conversion.
Mixed image-type support
Use the same tool for photos, anime, illustrations, product images, and screenshots according to the site’s examples and FAQs.
Use cases
Old photo cleanup
Restore older family photos or scans before archiving, sharing, or sending them to print. The upscaling step can make the image clearer before any deeper restoration work.
Product image enhancement
Improve marketplace listings, product galleries, and ad creatives when the original image is too small for modern ecommerce presentation.
Anime and illustration upscaling
Enlarge manga, anime, and illustration files for wallpapers, mockups, or print-ready assets while preserving lines and color areas more cleanly than a basic resize.
Batch image processing
Process several images together when you have a backlog of scans, product shots, or creative files that all need a higher-resolution export.
Quality checks before paid output
Use the free 200% option to evaluate quality on a specific image before deciding whether to pay for a 2K or 4K export.
