Image Converter — Convert Image Formats Free
Convert between JPG, PNG and WebP in your browser — batch convert, control quality, and set a background for transparent images. 100% private.
JPG has no transparency — a background colour is used when converting transparent PNGs to JPG.
What is an Image Converter?
An image converter is a free online tool that changes a picture from one file format to another — for example PNG to JPG, JPG to WebP, or WebP to PNG. Different formats suit different jobs: JPG is small and universal for photos, PNG is lossless and supports transparency for logos and graphics, and WebP is a modern format that gives the smallest files at great quality. Converting lets you pick the right format for wherever the image is going — a website, a form, a print, or an app that only accepts certain types.
DebugSpot's Image Converter works entirely in your browser. Your images are read and re-encoded on your own device using the HTML Canvas — nothing is uploaded to a server. That makes it completely private for personal photos, screenshots, and confidential graphics. You can convert many images at once (batch), control the quality for lossy formats, and choose a background colour when converting a transparent PNG to JPG.
Unlike many converters, there is no signup, no watermark, no daily limit, and no cost. It works on Windows, macOS, Linux, Android, iPhone, and Chromebook in any modern browser — with nothing to install.

- Go to debugspot.com/image-converter
- Drag your images in (or click to browse)

Step-by-Step Guide
Everything you need to know — in under a minute.
Add your images
Drag and drop your images onto the box, or click to select several at once. JPG, PNG, WebP and other browser-readable formats are supported. Nothing is uploaded.
Choose the output format
Select JPG (smallest for photos, no transparency), PNG (lossless, keeps transparency), or WebP (smallest overall, keeps transparency).
Set quality / background (optional)
For JPG and WebP, use the quality slider to balance size and detail. When converting a transparent PNG to JPG, choose the background colour that fills the transparent areas.
Download your converted images
Each image shows the format change and file size. Download them individually, or click Download All to save the whole batch.
How Does It Work?
📥 Local reading
Your images are read directly from your device with the browser File API. Nothing is sent over the internet.
🖼️ Canvas re-encoding
Each image is drawn onto an HTML canvas and re-encoded in the format you choose, producing a clean converted file.
🎨 Transparency handling
PNG and WebP keep transparency. When converting to JPG (which has no alpha channel) the transparent areas are filled with your chosen background colour.
📤 In-browser download
Converted images stay in your browser's memory and download on click. Close the tab and everything is cleared — nothing is stored anywhere.

Tips & Best Practices
✅ Use WebP for the web
WebP gives the smallest files at similar quality — great for websites and saving space.
✅ Use PNG for transparency
If your image needs a transparent background (like a logo), keep it as PNG or WebP, not JPG.
✅ Set a background for PNG→JPG
JPG can't store transparency, so pick a background colour that suits your image before converting.
✅ 80–90% quality is ideal
For JPG and WebP, 80–90% quality looks great while keeping files small.
✅ Convert then compress
After converting, run the result through our Image Compressor for even smaller files.
✅ Keep your originals
Conversion is one-way for lossy formats; keep the originals in case you need them later.

Frequently Asked Questions
Is this image converter completely free?
Yes — it is 100% free with no signup, no limits, and no watermark. Ads on the page keep it free for everyone.
Are my images uploaded to a server?
No. All conversion happens in your browser using the HTML Canvas. Your images never leave your device, which makes it safe for private pictures.
Which formats can I convert between?
You can convert between JPG, PNG, and WebP in any direction, and convert from other browser-readable formats (like BMP or GIF) into these.
How do I convert PNG to JPG?
Add your PNG, choose JPG as the output, pick a background colour for any transparent areas, and download. JPG produces a smaller file for photos.
How do I convert to WebP?
Add your images, select WebP as the output format, and download. WebP usually produces the smallest files at great quality.
Can I convert WebP to JPG or PNG?
Yes. Add your WebP image, choose JPG or PNG as the output, and download — handy for older apps that don't support WebP.
What happens to transparency when I convert to JPG?
JPG can't store transparency, so transparent areas are filled with the background colour you choose. Convert to PNG or WebP to keep transparency.
Can I convert many images at once?
Yes. Add as many images as you like, set the format once, and download them all with Download All.
Do the converted images have a watermark?
No. The output contains only your image in the new format, with no branding or watermark.
Does it work on my phone?
Yes. It works in Chrome on Android and Safari on iPhone and iPad, as well as every desktop browser.
Can it convert HEIC photos from my iPhone?
Conversion relies on formats your browser can decode. Modern JPG, PNG, and WebP work everywhere; HEIC support depends on your browser and device.
What's the difference between converting and compressing?
Converting changes the file format; compressing reduces the file size. Use our Image Compressor to compress, and often both together for the web.
