Stop Using Blurry, Low-Resolution Photos

Low-quality images can make even the best content look unprofessional. PDFCraftor uses advanced algorithms to upscale your images, adding pixels and improving clarity effortlessly.

Pixelation

Images look "blocky" when enlarged, ruining their appearance.

Poor Clarity

Old photos or small web images lack sharp details and look fuzzy.

Unsuitable for Print

Low-res files look blurry on physical paper or merchandise.

Expert Tips for Best Results

Start with the Best Possible File

Upscaling works best on images that aren't already heavily compressed.

Avoid Over-Enhancing

If an image is extremely tiny (e.g., 50px), upscaling it to 4000px may look artificial. Moderate increases yield the most natural results.

Frequently Asked Questions

PDFCraftor's Image Upscaler uses advanced interpolation algorithms to increase the resolution of your images. It analyses the existing pixels and intelligently fills in new details to produce a sharper, larger version of your photo.
You can upscale images by 2x or 4x their original resolution. For example, a 500×500 image can be enlarged to 1000×1000 (2x) or 2000×2000 (4x).
Our upscaler uses smart algorithms to minimise blurriness. While extreme upscaling of very low-resolution images may show some softness, most images upscaled by 2x produce excellent results with preserved sharpness.
You can upscale JPG, PNG, and WEBP images. The output retains the same format as your original file, preserving transparency for PNG and WEBP images.
