How to Use
Drag and drop your JPG or JPEG file, click to browse, or paste from clipboard (Ctrl+V). Supports files up to 20 MB.
PNG is selected by default. PNG is lossless — there is no quality slider because PNG preserves every pixel exactly as-is. The converted file will be larger than the original JPG.
Use Advanced Options to resize during conversion. Set a max width or height and the tool maintains your aspect ratio automatically.
Click "Convert Now" for instant in-browser conversion. Compare before and after with the slider, then download your PNG.
Why Convert JPG to PNG?
While JPG is the dominant format for photographs, PNG is preferred in several important scenarios. PNG uses lossless compression — every pixel is preserved exactly with no quality degradation. This makes PNG the right choice for logos, icons, screenshots, graphics with text, and any image that needs to be edited and re-saved multiple times without accumulating compression artifacts.
The most compelling reason to convert JPG to PNG is for image editing. Every time you save a JPG, it re-compresses and loses quality. If you're making repeated edits, working in PNG preserves quality through each save cycle. Once you're done editing, you can convert back to JPG for final delivery.
Important: JPG to PNG Won't Improve Quality
Converting a JPG to PNG does not improve or recover quality. PNG will perfectly preserve the existing quality of your JPG — including any compression artifacts already present. Think of it as "locking in" the current quality to prevent further degradation during editing, not as an enhancement.
If your JPG already has visible compression artifacts (blocky areas, color banding), those will still be present in the PNG output. This is expected and normal.
PNG and Transparency
Unlike JPG, PNG supports full alpha channel transparency. However, converting a JPG to PNG does not create transparency — JPG has no transparency data to convert. The PNG output will have a fully opaque background. To create a transparent background, you would need a separate background removal step.
File Size Expectation
PNG files are significantly larger than equivalent JPG files. A 500 KB JPG photo might become a 2–4 MB PNG. This is normal and expected — PNG's lossless compression simply stores more data. Use PNG when quality preservation matters, and JPG when file size matters.
Frequently Asked Questions
No. Converting JPG to PNG preserves the current quality exactly but cannot recover quality that was lost during the original JPG compression. If your JPG has compression artifacts, those will be present in the PNG too. The benefit is that the PNG won't lose any additional quality on future saves — it "locks in" the current state losslessly.
PNG uses lossless compression, which stores all pixel data without discarding anything. JPG uses lossy compression, achieving smaller files by selectively discarding detail. A typical JPG photo at 85% quality stores roughly 10–20% of the original raw image data, while PNG stores close to 100%. This is why PNG files are 3–8 times larger than their JPG equivalents.
Use PNG for: logos and icons (need sharp edges), screenshots with text, images that need to be edited repeatedly, graphics with transparency, and any image where pixel-perfect quality matters. Use JPG for: photographs being shared or published, any image where file size matters more than maximum quality, and web images that don't need transparency.
No. Converting a JPG to PNG does not create transparency. JPG has no alpha channel — all pixels are fully opaque. The PNG output will have the same fully opaque background as the JPG. To remove a background and create transparency, you need a background removal tool, not a format converter.
PNG is a lossless format — there is no quality setting because PNG always preserves 100% of the image data. Quality sliders only apply to lossy formats like JPG and WebP, where you trade image quality for smaller file size. PNG simply stores exactly what it receives.
Yes. Use the Batch Mode tab to upload up to 20 JPG files at once. All files are converted sequentially in your browser and you can download them all as a single ZIP file when done.
100% in your browser. No server, no upload, no internet required after the page loads. The conversion uses the HTML5 Canvas API — your images are processed entirely on your device. This makes it fast, private, and secure.
Yes. Open the Advanced Options section and enable resize. Set a maximum width and/or height in pixels. The tool will maintain your original aspect ratio by default, scaling the image down proportionally to fit within your specified dimensions.
