About JPG and PNG Formats
- JPG (JPEG) and PNG are two of the most common image formats, built for different jobs. JPG uses lossy compression to make photos small, which is ideal for cameras and web images but discards some detail. PNG uses lossless compression, preserving every pixel, and supports transparency — making it the go-to for graphics, logos, screenshots, and editing. Converting a JPG to PNG gives you a lossless copy that won't degrade further with editing, though it will usually be a larger file. We built this tool to make that conversion instant, free, and fully private — your images are processed on your own device, never on a server.
How to Convert JPG to PNG
It takes seconds. Drag and drop your JPG files onto the page, or click to browse and select them from your device. The tool converts each image to PNG automatically and prepares the results for download. Add a single photo or a whole batch at once. When conversion finishes, click Download to save your PNG files individually or together. Nothing is uploaded — every image is converted on your own device, so your photos stay private.
Common Mistakes to Avoid
❌ Expecting transparency to appear from nowhere
✓ Solution:
Converting a JPG to PNG doesn't add transparency, because the original JPG has none — it has a solid background. PNG supports transparency, but you'd need to edit the image to remove the background afterward.
❌ Assuming PNG will restore lost JPG quality
✓ Solution:
Detail already discarded by JPG compression can't be recovered by converting to PNG. The PNG will be lossless from that point on, but it can't bring back what the JPG already threw away. Start from the best-quality JPG you have.
❌ Being surprised by the larger file size
✓ Solution:
PNG is lossless, so it's usually bigger than the JPG, especially for photos. That's expected. Use PNG when you need quality or transparency, and keep JPG when small file size matters more.
❌ Using PNG for large photos on the web
✓ Solution:
For photographs on websites, PNG files can be needlessly heavy and slow to load. PNG shines for graphics, logos, and screenshots; for web photos, JPG or WebP is often the better choice.
❌ Uploading private images to unknown converters
✓ Solution:
Many online converters send your files to their servers. For personal or sensitive images, use a tool that converts locally in your browser so your pictures never leave your device.
Frequently Asked Questions
PNG is lossless and supports transparency, making it better for image editing, graphics, logos, and screenshots, and it's required by some platforms. Converting gives you a copy that won't gain new compression artifacts as you edit. JPG stays best when you need the smallest file size for photos.
No. Converting can't recover detail the original JPG already lost to compression. What it does is stop further quality loss — the PNG is lossless from that point, so edits and re-saves won't degrade it the way JPG would.
PNG uses lossless compression, which preserves every pixel and typically produces bigger files than JPG's lossy compression, especially for detailed photos. The larger size is the trade-off for full quality and transparency support.
Yes. Drag in a batch and the tool converts them together, letting you download each PNG or all of them at once. This is ideal for preparing a set of images for design work, a website, or an upload in a single pass.
No. All conversion happens locally in your browser using your device's own processing — your images are never uploaded, stored, or seen by anyone, including us. That makes the tool safe for personal and private images. Once you close the tab, nothing remains.
