FAQ

Frequently Asked Questions

What formats are supported?
Upload .pdf files and .png, .jpg, .jpeg, .webp, .gif, .bmp, .tiff, .heic, or .heif cover images. The new image replaces the existing cover in the PDF while preserving all other content.
Is there a file size limit?
PDF files up to 50-200 MB and cover images up to 10-40 MB (adjusted based on your device memory). All processing happens locally in your browser, so speed depends on your device.
Are my files uploaded anywhere?
No. PDF Cover Changer processes everything client-side using JavaScript. Your PDF and images never leave your device — complete privacy by design.
What image dimensions should I use?
Most e-readers display covers at 1600 x 2560 pixels (roughly 2:3.2 ratio). Use that resolution or higher for the sharpest results across all devices.
How to change PDF cover on iPhone?
Open this page in Safari or Chrome on your iPhone. Tap the left slot to choose your PDF file from the Files app, tap the right slot to pick your new cover image from Photos, then tap Change. The new PDF downloads to your Files app — open it and the new cover appears immediately.
Can I change PDF cover on Kindle?
Yes. Change the new PDF cover on any device using this tool, then send the updated PDF file to your Kindle via Send to Kindle, email, or USB cable. This works for Kindle Paperwhite, Oasis, Scribe, and the Kindle app.
How to change PDF cover without Calibre?
