Why PDNob Is the Best Way to Convert PNG to Searchable PDF
Accurate PNG Text Recognition Powered by ABBYY OCR Technology
PDNob is built on ABBYY's industry-leading OCR engine, which reads the text inside your PNG images — whether they're screenshots, photographed pages, or design exports — and turns PNG to searchable PDF you can select, copy, and edit without retyping a single word.
16+ Supported Languages
PDNob recognizes text in PNG images across 16+ languages — including English, Chinese (Simplified & Traditional), Japanese, Korean, Arabic, French, German, Spanish, Russian, Portuguese, Italian, Dutch, Turkish, Indonesian, and Thai — so multilingual PNGs become searchable PDFs in one pass.
Works Well with Low-Quality PNG Images
Blurry screenshots, low-resolution photos, or faded scans saved as PNG are no problem — PDNob's cloud OCR engine still reads the text and easily convert PNG to searchable PDF. Just upload your image and let the AI handle the rest.
Your PNG Files Stay Private
Every PNG you upload travels over a TLS-encrypted connection and is automatically removed from our servers once the conversion finishes — keeping your images and the converted PDF confidential the whole way through.
Who Can Benefit from Converting PNG to Searchable PDF?
Education
Students and teachers who save lecture slides, handwritten notes, or textbook pages as PNG screenshots can convert them to searchable PDFs, making it easy to highlight key points and find information while studying.
Multilingual Use
Translators and researchers who collect foreign-language images can convert PNG to searchable PDF to quickly locate specific terms and copy text for translation, instead of retyping content by hand.

FAQs about Converting PNG to Searchable PDF
Can I convert screenshot as PNG to searchable PDF online?
Yes. Upload your PNG screenshot to PDNob, select the recognition language, and click "OCR PDF." The AI-OCR engine analyzes the image and outputs a PDF where the text becomes selectable, searchable, and ready to copy.
Will converting PNG to a searchable PDF change how the image looks?
No. PDNob keeps the original visual layout of your PNG and adds an invisible text layer underneath it. The resulting PDF still looks like your image, but the text inside can now be searched, highlighted, and copied.
What's the difference between a regular PNG to PDF conversion and a searchable PDF?
A standard PNG to PDF conversion simply places the image on a PDF page, so any text remains part of the picture and can't be selected. A searchable PDF created with OCR adds a hidden, recognized text layer on top of the image, letting you search, select, and copy the text directly.
Can PDNob recognize text in PNG images with tables or multiple columns?
Yes. PDNob's ABBYY-powered OCR engine is designed to handle structured content such as tables, columns, and forms inside PNG images, preserving the general layout while extracting the text into a searchable PDF. Clear, high-resolution PNGs give the best results.

Can I convert several PNG files into one searchable PDF at once?
The online tool processes one PNG at a time to keep each conversion fast and accurate. If you regularly need to combine multiple images or process several files together, the PDNob desktop app offers batch conversion features for larger workloads.
What other image formats can I convert to a searchable PDF besides PNG?
In addition to PNG, PDNob's OCR tool also supports JPG, JPEG, TIFF, and BMP image files, as well as scanned PDF documents — so you can convert PNG to searchable PDF or any of these formats using the same workflow.
