What is the PNG to JPG Converter — Free & Private?
PNG to JPG Converter
Convert PNG images to JPG (JPEG) instantly and privately. PNG is great for graphics and screenshots, but its lossless files are large; JPG produces much smaller files that are ideal for photos, email attachments and sites with upload size limits.
Because every conversion runs through the browser's own canvas engine, your images never leave your device — there is no upload, no queue, and no server that could retain a copy.
Why convert PNG to JPG
- Smaller files — JPG compression can shrink a photo-like PNG by 70–90%.
- Universal compatibility — every device, editor and upload form accepts JPG.
- Adjustable quality so you decide the balance between size and sharpness.
Note: JPG can't store transparency, so transparent PNG areas are filled with a background colour you choose (white by default).
How it works
How PNG to JPG Conversion Works
The tool decodes your PNG, paints it onto a canvas over a solid background, and re-encodes it as a JPG at your chosen quality.
Steps
- Drop one or more PNG files (other formats work too).
- The output is preset to JPG — set the quality and the background used to fill transparent pixels.
- Click Convert and download.
Behind the scenes
decode(png) -> fill background -> draw -> encode("image/jpeg", quality)
Because JPG is lossy, lower quality means smaller files. Most photos look great around 80–85%.
Examples
Photo PNG to compact JPG
A photo saved as PNG is converted to JPG at 85% quality for a much smaller file.
Transparent logo on white
A transparent PNG logo is flattened onto a white background and saved as JPG.
Frequently asked questions
Will transparency be preserved?
Will transparency be preserved?
No — JPG does not support transparency. Any transparent area in your PNG is filled with the background colour you select (white by default) so it doesn't turn black.
What quality should I use?
What quality should I use?
For photos, 80–85% is a great balance of size and quality. For graphics with text or sharp edges, use 90%+ or keep them as PNG instead.
Is there a file size or count limit?
Is there a file size or count limit?
You can convert up to 30 PNGs at once, each up to 25 MB. Everything runs in your browser, so larger batches simply depend on your device's memory.
