Can I upload the PDF file itself?

Not directly: the upscaler reads images. Export the page from your PDF reader (Save as image, Export, or print to PNG) or take a screenshot, then upload that file. Your reader rasterizes the page, and this tool then enlarges that image.

How do I get the sharpest result from a scanned PDF?

Export the page so it keeps as much of the scan detail as possible, then start at 2x. For a phone photo of a paper page, use our [photo upscaler](/tools/photo-upscaler) and check that the text is still readable.

Will the text stay readable after upscaling?

At 2x to 4x, check stroke edges and table lines first. If the edges look soft, lower the scale; the model cannot recover text that is not in the source.

What file types and size limits apply?

JPG, PNG, WebP, and GIF up to 10MB per image. If an exported page is larger than that, lower the export resolution or crop the page before uploading.

Can I upscale every page of a long document?

Export each page as its own image. Paid batch takes 2-8 images at a time. If your files are already separate images, the [JPG](/tools/jpg-upscaler) or [PNG upscaler](/tools/png-upscaler) does the same job.
