# Image Converter Online Free — Convert JPG, PNG & WebP

Convert images between JPG, PNG and WebP in one batch, with quality control and transparency handled for you. Free image converter in your browser.

Updated July 2026 · Reviewed by the PDFWix Team (https://www.pdfwix.com/about/team)

Different places accept different image formats. Older software and many upload forms only take JPG, designers need PNG for transparent logos, and websites load fastest with WebP. The PDFWix image converter turns JPG, PNG, WebP, GIF and BMP files into JPG, PNG or WebP in your browser. Choose the output, set the quality for lossy formats and convert a whole folder at once.

To convert an image free: open the PDFWix Image Converter, add your files, choose JPG, PNG or WebP as the output, adjust quality if needed, and click Convert. For one-click presets use [WebP to PNG](/webp-to-png), [WebP to JPG](/webp-to-jpg), [PNG to JPG](/png-to-jpg) or [JPG to PNG](/jpg-to-png).

## JPG vs PNG vs WebP: which format should you use?

JPG is the universal photo format: every device, app and upload form opens it, and lossy compression keeps photos small — but it has no transparency and softens sharp text and line art. PNG is lossless and supports transparency, making it ideal for logos, screenshots, diagrams and anything with crisp edges, at the cost of much larger files for photos. WebP, developed by Google, does both: lossy or lossless compression, transparency, and files typically 25–35% smaller than JPG at the same visual quality. It is supported by all modern browsers, but some older software still refuses it. Rule of thumb: photos for sharing → JPG; graphics, screenshots and anything transparent → PNG; images for your own website → WebP.

## How to convert an image

1. 1
   ### Add images
   Drop JPG, PNG, WebP, GIF or BMP files — mix formats freely.
2. 2
   ### Choose the output format
   Pick JPG, PNG or WebP.
3. 3
   ### Set quality
   For JPG and WebP choose a quality (92% is near-original). PNG is always lossless.
4. 4
   ### Convert and download
   Click Convert. Files keep their names with the new extension.

## Tips for converting images

### Keep logos as PNG or WebP

JPG cannot store transparency and will add a white background.

### Don't round-trip JPG

Converting JPG → PNG won't restore lost detail; it only makes the file bigger.

### Shrink after converting

Use Compress Image (https://www.pdfwix.com/compress-image) for tight size limits.

### iPhone photos

HEIC files are handled by HEIC to JPG (https://www.pdfwix.com/heic-to-jpg).
