FORMAT GUIDE

Choosing the Right Image Format for Your Use Case

Each image format is designed for specific performance and visual trade-offs. Here is how they compare:

WebP — Modern Web Standard

Developed by Google, WebP provides superior lossless and lossy compression for web images. WebP files are on average 26% smaller than PNGs and 25-34% smaller than comparable JPEGs while supporting 24-bit RGB with alpha transparency.

  • Recommended for all modern websites and blogs
  • Fully supported in Chrome, Safari, Firefox, and Edge
  • Supports both lossy and lossless modes with alpha channel

PNG — Lossless & Transparent

PNG is an uncompressed, lossless bitmap format that preserves exact pixel values and full 8-bit alpha transparency. It is the premier choice for company logos, app icons, digital screenshots, and detailed diagrams.

  • Sharp text, clean edges, and zero compression artifacts
  • Full transparent background support
  • Universal editing support in Photoshop, Figma, and Canva

JPG / JPEG — Universal Photography

JPG is the world's most widely recognized image format. It uses lossy discrete cosine transform compression to achieve compact file sizes for complex photographs and real-world scenes.

  • 100% compatibility across all legacy operating systems and email clients
  • Adjustable quality ratio from 10% to 100%
  • Ideal for photo albums, digital cameras, and social media uploads

ICO — Website Favicons & App Icons

The Windows ICO format encapsulates multi-resolution icon bitmaps into a single container file. Essential for web development to display custom brand marks in browser tab headers and bookmarks.

  • Standard format for website `favicon.ico` files
  • Supports 32-bit RGBA true color with transparent pixels
  • Standard sizes: 32×32, 64×64, and 128×128 px

FREQUENTLY ASKED QUESTIONS

Frequently Asked Questions

Everything you need to know about converting images online with We Make PDF.

Which image formats can I convert between?

We Make PDF supports converting between all major image formats, including JPG (JPEG), PNG, WebP, GIF, BMP, Windows ICO (favicons), AVIF, and SVG. You can convert JPG to WebP, PNG to WebP, WebP to PNG, JPG to PNG, PNG to JPG, or any image to ICO format.

Can I convert multiple images at once (batch conversion)?

Yes! You can upload up to 30 images simultaneously. You can set a global target format for all images or customize the target format individually for each file, then download them all at once as a convenient ZIP file.

Does converting from PNG to WebP or JPG keep transparency?

WebP, PNG, and GIF fully preserve alpha transparency. When converting transparent images to formats that do not support transparency (such as JPG or BMP), We Make PDF automatically blends the background with your choice of solid white or black to ensure clean, professional results without dark artifacts.

Are my photos or images uploaded to any remote server?

Never. We Make PDF processes all images 100% locally inside your device browser memory via HTML5 Canvas and JavaScript. Your personal photos, client designs, and proprietary graphics never leave your computer or phone.

How can I convert an image to an ICO favicon for my website?

Simply upload any JPG, PNG, or WebP image and select "ICO" as your target format. We Make PDF generates a compliant Windows ICO binary file containing standard 32-bit RGBA icon dimensions (32×32, 64×64, or 128×128 px) ready to drop into your website as `favicon.ico`.

Why should I convert my JPG and PNG images to WebP?

WebP is a modern web format engineered by Google that offers 25% to 35% smaller file sizes than JPG and PNG at identical visual quality. Converting to WebP dramatically boosts website loading speed, reduces bandwidth consumption, and improves Google Core Web Vitals and SEO scores.
