Everything you need to convert JPG to PNG
Powerful features designed for speed, privacy, and unlimited usage — all running entirely in your browser.
Lossless Quality
PNG uses lossless compression, so your converted image retains every pixel of detail from the original JPG with zero quality degradation.
Transparency Support
Unlike JPG, PNG supports alpha transparency channels. Convert your JPG and add transparent backgrounds for logos, icons, and graphics.
100% Private
All conversion happens locally in your browser using the Canvas API. Your images are never uploaded to any server — zero data leaves your device.
Unlimited Conversions
No daily limits, no conversion credits, no file count restrictions. Convert as many JPG files to PNG as you need, completely free.
Batch Processing
Convert multiple JPG images to PNG in one go. Drop several files and process them all simultaneously without waiting in a queue.
No Watermarks
Your converted PNG files are clean and unmarked. We never add watermarks, logos, or any branding to your output images.
Why convert JPG to PNG?
Discover the key advantages of switching from JPG to PNG format.
Perfect for Web Graphics
PNG is the web standard for graphics requiring transparency — logos, UI elements, icons, and illustrations all benefit from PNG format.
Ideal for Editing
PNG files preserve full color depth and detail, making them perfect for further editing in Photoshop, GIMP, or any image editor without quality loss.
Better for Text & Sharp Edges
JPG compression creates artifacts around text and sharp edges. PNG preserves crisp lines and readable text in screenshots and diagrams.
No Re-compression Artifacts
Each time a JPG is saved, it loses quality. Converting to PNG stops this cycle — your image quality is locked in permanently.
Works Offline
Once the page loads, the converter works without an internet connection. Perfect for sensitive images or when working in restricted environments.
Zero Cost Forever
No subscriptions, no trial limits, no hidden fees. Convertly is funded by ads and donations — the tools are always free for you.

Tips for best results
Get the most out of your JPG to PNG conversions with these expert tips.
Add Transparency After Conversion
Once your JPG is converted to PNG, use an image editor to remove backgrounds and add transparency — something JPG cannot support.
Watch File Size
PNG files are typically larger than JPG because they use lossless compression. Consider if lossless quality is necessary for your use case.
Use PNG-8 for Simple Graphics
For images with fewer than 256 colors (like logos or icons), PNG-8 produces much smaller files than PNG-24 while remaining lossless.
Batch Convert for Efficiency
If you have many JPG files, use the batch upload feature to convert them all at once rather than one at a time.
Check Color Profiles
PNG supports ICC color profiles. If color accuracy matters, ensure your source JPG has an embedded sRGB profile for consistent results.
JPG vs PNG
Understand the differences between these two image formats.
JPG
Source format
JPEG (Joint Photographic Experts Group)
A widely used lossy image format ideal for photographs and complex images with millions of colors. JPG achieves high compression ratios, making it the standard for web photos.
PNG
Target format
PNG (Portable Network Graphics)
A lossless image format that supports transparency and up to 48-bit color depth. PNG is the preferred format for web graphics, logos, screenshots, and images requiring precise detail.
Frequently asked questions
Everything you need to know about converting JPG to PNG.
Is the JPG to PNG converter really free?
Yes, completely free with no limits. Convert as many JPG files to PNG as you want — no daily caps, no signup, no watermarks, and no hidden fees. Convertly is supported by ads and optional donations.
Does converting JPG to PNG improve image quality?
Converting JPG to PNG does not add detail that was already lost to JPG compression. However, it prevents further quality loss since PNG is lossless. The converted PNG will look identical to the source JPG but will not degrade with future saves.
Will my images be uploaded to a server?
No. The entire conversion happens in your browser using the HTML5 Canvas API. Your JPG images are never uploaded, stored, or transmitted anywhere. They stay on your device at all times.
Can I convert multiple JPG files at once?
Yes, our converter supports batch processing. Simply drag and drop multiple JPG files onto the tool area, and they will all be converted to PNG simultaneously. You can download them individually or as a ZIP archive.
What is the difference between JPG and PNG?
JPG uses lossy compression (smaller files, some quality loss) and does not support transparency. PNG uses lossless compression (larger files, no quality loss) and supports alpha transparency. JPG is better for photos; PNG is better for graphics, logos, and images with text.
Can I add a transparent background to my converted PNG?
The converter preserves the original image as-is. To add transparency, use an image editor like Photoshop, GIMP, or an online background remover after converting your JPG to PNG. PNG format supports transparency, but the converter does not automatically remove backgrounds.
What is the maximum file size I can convert?
There are no artificial file size limits. The only constraint is your device's available memory (RAM). Most modern browsers can handle JPG files up to several hundred megabytes without issues.
Does the converter work on mobile devices?
Yes, the JPG to PNG converter works on all devices — desktop, laptop, tablet, and mobile phones. The interface is fully responsive and optimized for screens as small as 358px wide.
