What to expect when converting PNG to PDF
A 1 MB PNG typically becomes 1 – 1.1 MB as PDF.
Quality: Lossless — the PNG is embedded inside the PDF without re-encoding.
Heads up: PDF doesn't support transparency, so transparent backgrounds in your PNG will be flattened (usually to white).
Best for: sharing graphics, screenshots, or logos via PDF-required channels.
Avoid when: the recipient prefers raw images.
Tip: PDFs flatten PNG transparency (typically to white). If transparency matters, share the PNG directly.
Place PNG Images into PDF Documents
Turn screenshots, scans, product images, or diagrams into a document format that is easier to print, email, archive, or review.
Select one or more PNG images — scanned pages, photos, screenshots, or diagrams. Upload multiple files to create a multi-page PDF document from several images.
Each image is placed onto a standard page (A4 or Letter) and scaled to fit while maintaining the original aspect ratio. Image quality is preserved at the source resolution — no downsampling.
Download your PDF document ready for printing, emailing, or archiving. All images are embedded at full quality inside the document.
Why Convert PNG to PDF
PDF preserves exact page layout, fonts, images, and formatting on every device and operating system. Your document looks identical whether viewed on a phone, laptop, or printed on paper.
Every computer, phone, and tablet can open PDF files using built-in viewers. Chrome, Safari, Edge, and Firefox all render PDFs natively without requiring Adobe Acrobat or any additional software.
PDF supports fillable form fields, dropdown menus, checkboxes, and digital signature fields. Businesses use PDF forms for contracts, applications, and surveys that can be completed electronically.
PDF includes built-in support for cryptographic digital signatures that verify document authenticity and detect tampering. Legal, financial, and government documents rely on PDF signatures for validity.
PDF supports CMYK color, spot colors, bleed marks, and trim boxes required by professional printers. PDF/X variants are the industry standard for submitting files to commercial print shops.

About the PNG Format
PNG (Portable Network Graphics) is a lossless image format created in 1996 as a patent-free replacement for GIF. It uses DEFLATE lossless compression, meaning every pixel is preserved exactly as intended — no visual information is discarded during encoding. PNG was developed by the web community and standardized by the W3C and ISO, making it one of the most trusted and universally supported image formats available.
PNG is best suited for screenshots, graphics, logos, and any image that requires transparency. Its support for a full alpha channel allows smooth, semi-transparent edges that blend seamlessly with any background. The main trade-off is file size — PNG files are significantly larger than JPEG for photographic content because no visual data is discarded. PNG does not natively support animation; for animated sequences, APNG (Animated Portable Network Graphics) serves as its extension.
