Why PNG? When to choose it over JPG
Both are image formats, but they serve different purposes:
Choose PNG when you need pixel-perfect quality — screenshots, UI mockups, documents with text, charts, or logos. PNG is lossless, so there are no compression artifacts around text edges.
Choose JPG when file size matters more than crispness — photos, colorful images, or attachments where smaller files are preferred. You can use the PDF to JPG tool for that.
For most document conversions, PNG gives you the sharpest results.
Real-world ways people use PNG and PDF conversion
Designers: Share mockups as documents
You've created a series of UI screenshots or wireframe PNGs. Package them into a single PDF to share with your client — organized, paginated, and easy to review.
Teachers: Create handouts from screenshots
Captured step-by-step instructions as screenshots? Convert them to a PDF handout that students can follow along with.
Professionals: Pull pages from reports for presentations
Need a single chart from a 30-page report for your slide deck? Convert just that page to PNG and insert it into your presentation — crisp and clean.
Tips for better results
Mixed image formats? No problem
If you have a mix of PNG, JPG, and other formats, use the Image to PDF tool. It accepts all common image formats and combines them into one PDF.
Compress after converting
If your PNGs are high-resolution, the resulting PDF can be large. Use Compress PDF to reduce the file size without visible quality loss.
Need searchable text?
After converting PNGs of text to PDF, the document contains images — not selectable text. If you need to search or copy text, run OCR on the converted PDF. Read our OCR guide for more details.
