How to convert IMAGE to JPEG
Converting an image to JPEG is the most common image format conversion task, and it matters because JPEG's lossy compression dramatically reduces file sizes for photographs: a 10 MB PNG of a photo can typically compress to under 500 KB as a JPEG at quality 85 without noticeable degradation. JPEG is also universally supported by every browser, email client, and image viewer.
This converter processes your image in the browser using WebAssembly. Your file never leaves your device, and there is no server upload size limit. Supported source formats include PNG, WEBP, AVIF, BMP, GIF, TIFF, and HEIC. The quality slider lets you balance output file size against image detail.
Upload your image
Click to select or drag in your source image. PNG, WEBP, AVIF, BMP, GIF, TIFF, and HEIC are all accepted.
Set JPEG quality
Choose a quality between 70 and 95. Quality 85 is a good default for photos. For graphics with flat color blocks, lower quality (70-75) may look fine and produce smaller files.
Convert in browser
The WebAssembly encoder decodes your source image and re-encodes it as JPEG. This happens locally with no network transfer.
Download the JPEG
Save the resulting .jpg file and verify it looks correct. Check the file size reduction in your system file manager.
Frequently asked questions
Will converting a PNG to JPEG reduce quality?
Yes. JPEG is a lossy format that permanently discards some image data during compression. For photographs, the quality loss at settings of 80 and above is typically imperceptible. For graphics with text, sharp edges, or flat color areas, the lossy compression can create visible artifacts.
Does JPEG support transparency?
No. JPEG cannot store transparent pixels. If your source image has a transparent background, the JPEG output will fill that area with a solid color, typically white. If you need transparency, use PNG or WEBP instead.
Is my image uploaded to a server?
No. The converter uses a WebAssembly codec running in your browser tab. Your file is processed in local memory and never transmitted.
What quality setting should I use for social media uploads?
Most social platforms re-compress your uploads anyway, so quality 85 is sufficient as a source. Uploading at maximum JPEG quality does not prevent the platform from applying its own compression on top.
Why is JPEG better than PNG for photographs?
JPEG exploits the fact that human vision is less sensitive to fine detail in high-frequency areas of a photo, allowing aggressive compression without visible quality loss. PNG's lossless compression is much less efficient for photographic content because it must preserve every pixel exactly.
