How to Use

  1. Upload your PNG image — Select or drag-and-drop a PNG image from your device.
  2. Adjust JPG quality — Use the quality slider (60%–100%) to balance file size and image quality. The output size updates in real time.
  3. Download JPG — Download the converted JPG file. Transparent areas are filled with white.

Why Use This Tool

PNG files are lossless and can be very large — a single screenshot or graphic can be 5–20MB. JPG uses lossy compression that reduces file sizes by 80–95% with minimal visible quality loss. When you don't need transparency, converting to JPG is the fastest way to shrink your files.

This tool gives you full control over the quality/size trade-off. The slider lets you adjust from 60% to 100% quality, and the output file size updates instantly so you can find the sweet spot. If your PNG has transparent areas, the tool warns you that they'll become white in the JPG.

Everything runs in your browser — your image never leaves your device. No server uploads, no accounts, no watermarks. Convert, preview the size savings, and download.

Frequently Asked Questions

Yes — JPG uses lossy compression which produces significantly smaller files than PNG's lossless format. A 5MB PNG might become a 200KB–800KB JPG depending on the quality setting. The trade-off is a small amount of compression artifacts, which are usually invisible at 80%+ quality.
JPG does not support transparency. Any transparent areas in your PNG will be filled with white in the JPG output. If you need to preserve transparency, keep your image in PNG format. This tool warns you if your PNG contains transparent pixels.
For most photos, 80%–85% gives an excellent balance of quality and file size — the compression artifacts are virtually invisible. Use 90%+ for images where quality is critical (print, portfolio). Use 60%–70% when file size matters most (email attachments, web upload limits).
No — all conversion happens entirely in your browser using the Canvas API. Your image never leaves your device. You can verify by disconnecting from the internet after the page loads — the tool continues to work.
This tool processes one image at a time so you can fine-tune the quality setting for each. After downloading one JPG, click "Convert Another" to process the next image. Each conversion takes less than a second.
