Step 1 Open the Files app on your iPhone and select the PDF document. Step 2 Tap and hold on to the PDF document; you will see a drop-down. Tap on Quick Actions Optimize File Size. The app will compress the PDF document to make it smaller and autosave it.
Go to File Options Advanced Image Size and Quality. Apply the image size and quality settings to the current document or to all new documents. Click Do not compress images in file. For default resolution, select High fidelity.
The best and easiest way to sharpen a PDF image is to simply scan the original document again. Often, blurry pages result from scanning errors, such as a bump to the machine or a dirty scanning plate. No amount of image editing and noise reduction will ever make such an image resolve more clearly.
Standard PDFs are not print-ready. They may have poor quality images and colors, which may not print correctly or print at a very low quality. You can use Acrobat Pro to create high-resolution print-ready PDFs from your standard PDFs.
How to convert from a PDF into an image file: Open your PDF in docHub Pro and choose file. Export it to the new file format by going to the right pane and choosing Export PDF tool. Choose image format type (e.g., JPG file, TIFF, etc.). Click Export. In Save As dialog box, save your file.
How do I create a high-resolution PDF? In the Save As PDF dialog box, click on Settings. In the Preflight dialog, select Save as PDF/X-4 and Click OK.
Open the website or app and log in to your account. Upload the document you want to upgrade the resolution of. You can do this by clicking on the Upload button and selecting the file from your computer or cloud storage. Once the document is uploaded, click on the Upgrade Resolution option.
