Choosing an image format
Format decides file size, quality, and whether transparency survives. Use this quick reference before you convert.
| Format | Best for | Transparency | Compression |
|---|---|---|---|
| PNG | Logos, icons, screenshots, sharp edges | Yes | Lossless |
| JPG | Photographs and complex color scenes | No | Lossy |
| WebP | Web images needing small size | Yes | Lossy or lossless |
| Base64 | Embedding a tiny icon directly in code | Keeps source format | Text, about 33% larger |
PNG keeps every pixel and supports transparency, so it suits graphics with text or flat color. JPG drops some detail to make photos far smaller, but cannot store transparency. WebP often beats both on size at similar quality. Base64 is not an image format; it is a text encoding that lets a small image live inside an HTML or CSS file.
How do I choose the right tool?
Match the tool to the job in front of you:
- Embedding a small icon or logo directly in HTML or CSS so the browser skips a request? Use the Image to Base64 Converter.
- Need an exact pixel size, such as a 1200 px content image or a square avatar? Use the Image Resizer with the ratio locked.
- File too heavy to email, upload, or post but the format must stay the same? Use the Image Compressor and start near 80% quality.
- Have a large PNG photo that does not need transparency? Use the PNG to JPG Converter for a much smaller file.
- Need transparency or a lossless copy of a photo? Use the JPG to PNG Converter.
- Want the smallest modern web image at good quality? Use the Image to WebP Converter.
- Adding a tab icon to your website? Use the Favicon Generator.
Why use Toolzent’s image & pdf tools?
Toolzent’s image & PDF tools are 100% free with no sign-up and nothing to install. They run privately in your browser using the built-in FileReader and an HTML canvas, so your images stay on your device and are never uploaded, logged, or stored, which makes them safe for confidential graphics and usable offline once the page has loaded. Results are instant, the layout is mobile-friendly, and every tool page shows a worked example. For instance, a 4000 by 3000 photo resized to width 800 gives a clean 800 by 600 image, and a 2 MB photo compressed at 80% quality often drops to a few hundred KB.

Frequently asked questions
Are these image & pdf tools free to use?+
Yes. Every image and PDF tool on Toolzent is 100% free with no account, no trial, and no usage limits.
Do I need to upload my images or install anything?+
No. The tools read your file locally in the browser, so nothing is uploaded to a server and there is nothing to install.
What is the difference between PNG, JPG, and WebP?+
PNG is lossless and keeps transparency, JPG uses lossy compression for smaller photos but has no transparency, and WebP gives small files with optional transparency, ideal for the web.
When should I convert PNG to JPG instead of compressing?+
Convert PNG to JPG when you want a much smaller photo and do not need transparency; compress when you must keep the same format but shrink the file size.
Why is a Base64 image bigger than the original file?+
Base64 turns every 3 bytes into 4 text characters, so the string is about 33% larger; a 30 KB image becomes roughly 40 KB of text you can paste into HTML or CSS.
Is my data private when I edit an image here?+
Yes. Encoding, converting, resizing, and compressing all happen in your browser with FileReader and an HTML canvas, so your files stay on your device and are never stored.
