FAQs
Answers before you export
Everything you need to know about using ImgConverter for png to pdf conversions.
Why convert PNG to PDF?
PDF is the universal standard for shareable documents that look identical on every screen, printer, and operating system. Converting images to PDF makes them easy to compile, print, email, and archive — with consistent formatting guaranteed across all platforms.
Will converting PNG to PDF reduce image quality?
PDF uses lossy compression. Use the quality slider (1–100) to find the best balance between file size and visual quality for your use case.
Does PDF support transparency?
No. PDF does not support transparency. Any transparent or semi-transparent areas in your PNG file will be filled with a white background in the converted result.
How many files can I convert at once?
ImgConverter supports batch conversion of up to 30 files per session. You can also set individual quality levels for each file in the batch using the per-file quality override.
Are my files stored after conversion?
No. All uploaded files and converted results are automatically and permanently deleted from our servers one hour after processing. Nothing is shared or retained.
