Everything you need in a free image upscaler

Increase image resolution

Upscale photos and graphics 2×, 3×, or 4× with progressive high-quality scaling — ideal for prints, zooms, and sharper displays.

Detail enhancement

Optional sharpening restores edge clarity after enlargement so upscaled images look crisper, not just bigger and blurrier.

100% browser-based

Everything runs locally on your device. Your images never upload to Focera servers — private by design.

Before & after preview

Compare the original and upscaled result with a slider, then download a PNG ready for design, social, or print workflows.

How It Works

Increasing image resolution should be fast and private. Focera keeps the whole flow on one page — upload, choose a scale, upscale, compare, and download without an account or desktop installer.

  1. Upload your image. Drag and drop a JPG, PNG, or WebP file up to 10 MB, or click the zone to browse from your device.
  2. Pick a scale factor. Choose 2×, 3×, or 4×, and optionally keep Enhance details on for sharper edges after enlargement.
  3. Upscale and download. Processing runs in your browser. Compare with the before/after slider, then download a PNG at the new resolution.

Jump back to the image upscaler anytime to process another file.

Popular Use Cases

  • Print and posters — Enlarge small photos so they hold up better when printed or displayed at larger sizes.
  • Product and marketplace listings — Increase resolution for zoom-friendly storefront images without reshooting.
  • Social and thumbnails — Stretch older assets to meet modern platform size requirements.
  • Design mockups — Upscale logos, screenshots, and graphics before dropping them into layouts.

  • AI Background Remover — Cut out subjects before or after increasing resolution.
  • Change Background — Replace the scene with a color, custom photo, or portrait blur.
  • Remove Watermark — Brush out logos or text overlays from photos you own.
  • Image Compressor — Shrink file size after exporting a larger PNG.
  • Image Converter — Convert between PNG, JPG, and WebP when your destination needs a specific format.
