Go to doitfree.online/tools/image-converter.html. No login or installation required — the tool runs entirely in your browser.
Click the upload area or drag and drop your image file. Supported input formats: PNG, JPG, and WebP. The image is loaded locally — it's never sent to any server.
Select your target format from the dropdown: JPG, PNG, or WebP. If you're converting for a website, WebP gives the best results.
Need a specific size? Enter the target width and height in pixels. You can also rotate the image 90°, 180°, or 270° if needed. The aspect ratio lock keeps proportions correct automatically.
For JPG and WebP output, you can set the quality level (1–100). Quality 80–85 gives the best balance of small file size and good visual quality for most use cases.

PNG files are lossless and often very large. If you're sharing a photo by email or uploading to social media, converting to JPG can reduce the file size by 60–80% with minimal visible quality loss.
WebP is Google's modern image format designed for the web. Switching your website images from JPG to WebP can significantly reduce page load times — an important factor for both user experience and Google Search ranking.
Different platforms have different ideal image dimensions. Use the resize feature to hit the exact pixel dimensions you need:
No. The Image Converter runs entirely in your browser using JavaScript. Your image files are never sent to any server — they stay on your device throughout the entire process.
The tool handles images up to around 20MB. For very large images, conversion may take a few seconds depending on your device's processing power.
JPG uses lossy compression, so some quality is lost. However, at quality settings of 80–90, the difference is invisible to most people. If you need a pixel-perfect copy, use PNG or WebP (which supports lossless mode).
The current version converts one image at a time. For bulk conversions, simply repeat the process for each file — each conversion takes under a second.
