ICO to PDF

Why convert ICO to PDF?

The main difference: ICO is a lossless format, while PDF is a document format. PDF is supported almost everywhere; ICO isn't.

Works on every device

Plenty of apps and websites can't read ICO (all browsers as a site icon). A PDF copy opens on any phone, tablet, computer or browser, so you can view, upload or send the picture without hunting for special software.

Transparent areas stay transparent

ICO and PDF both handle transparency, so anything see-through in the original is still see-through after conversion.

One file to print, email or submit

A PDF looks identical on every screen and printer, and it's the format most application forms, schools and offices want.

ICO vs PDF: what's the difference?

Property	ICO	PDF

Transparent background	Yes	Yes
Animation	No	No
Where it opens	All browsers as a site icon	All browsers and devices
Used for	Website favicons and Windows icons	Documents, printing, forms and sharing several pages as one file

What is an ICO file?

ICO is the icon format of Microsoft Windows and the classic format for website favicons - the little image in a browser tab. One ICO file can hold several sizes (16 × 16, 32 × 32, 48 × 48 and more), so the icon looks sharp everywhere.

ICO supports transparency, so icons can have rounded or irregular shapes. Modern sites often add PNG and SVG favicons too, but favicon.ico is still the universal fallback.

How to open an ICO file

Windows shows ICO files in File Explorer and opens them in Photos; Mac Preview opens them too. GIMP and online editors can edit them. To make one, convert a square PNG - or use the Favicon Generator for a complete set.

Extension: .ico
Sizes: Several in one file (16-256 px)
Transparency: Yes
Best for: Favicons, Windows icons

What is a PDF file?

PDF (Portable Document Format) was created by Adobe in 1993 to make documents look identical on every screen and printer. A PDF can contain text, vector graphics and images across any number of pages.

It's the standard for forms, contracts, resumes, school assignments and anything you print or submit. Turning photos and scans into a PDF bundles them into one tidy, universally readable file.

How to open a PDF file

Every web browser opens PDFs, as do Mac Preview, the Files app on iPhone and the free Adobe Acrobat Reader on Windows, Mac and Android. To get pictures out of a PDF, convert its pages to JPG or PNG.

Extension: .pdf
Contains: Text, vectors and images
Pages: One or many
Best for: Documents, forms, printing
