Free Image & PDF Upscaler
Enlarge photos, screenshots, logos, illustrations and selected PDF pages by 2×, 3× or 4× with high-quality resampling, controlled noise reduction and edge sharpening. Choose Auto, Photo, Text & Documents, or Artwork & Logos mode, compare the original with the enhanced result, and download PNG, JPEG, WebP or a rebuilt PDF. Processing happens locally in your browser: files are never uploaded, stored or watermarked.
Image and document enhancement modes
- Auto analyses edge density and colour variation to choose a safe profile.
- Photo keeps natural textures while reducing visible compression noise.
- Text & Documents prioritises readable letters, numbers and sharp scan edges.
- Artwork & Logos preserves flat colours, transparency and clean graphic edges.
PDF upscaling
Upload PDFs containing up to 40 pages, choose the pages to enhance, and download a new PDF. Enhanced pages are rasterised, so selectable text in those pages is not retained.
