How to Convert PNG to JPG
To convert PNG to JPG, upload your PNG file to the converter above, select JPG as the output format, and download the result — no software install required. JPG uses lossy compression, so the converted file is typically 60–80% smaller than the PNG, which makes it far better suited for email attachments, website photos, and social uploads. The one trade-off: JPG does not support transparency, so any transparent background in your PNG becomes solid (white by default).

Transparency is flattened onto a white background.

The whole process takes under two minutes and requires no software installation or account. Your original PNG file is never modified.
Upload your PNG file
Drag your .png file onto the converter above, or click “Browse files” to select it from your device. Files are processed locally in your browser whenever possible — nothing is uploaded to a server.
Confirm the output format is JPG
The converter defaults to PNG → JPG on this page. If you dropped in a different file type, set the target format to JPG (.jpg) using the format menu.
Adjust quality settings
Choose your quality settings. For photos, quality 90 is visually indistinguishable from the original; graphics with text or transparency should use the lossless option when available.
Convert the file
Click “Convert”. JoltFile processes the file and shows a progress indicator — most image conversions finish in a few seconds.
Download your JPG file
Save the converted .jpg file to your device. The original PNG file is never modified, and temporary data is discarded automatically.
What happens to quality when converting PNG to JPG?
Converting PNG to JPG is a lossless-to-lossy move. Photographic content survives the transition almost invisibly at quality settings of 85–95, but sharp edges, text, and flat-color graphics can pick up compression artifacts. Transparent pixels are flattened onto a background color, and the file size usually drops by 60–80%.
When should you convert PNG to JPG?
- Shrinking photo-heavy PNG exports before emailing or uploading
- Preparing images for platforms that reject or penalize large PNGs
- Reducing page weight for faster website load times
- Archiving screenshots where perfect fidelity no longer matters

About the PNG and JPG formats
What is PNG? (Portable Network Graphics)
PNG is a lossless raster image format created in 1996 as a patent-free replacement for GIF. It supports full alpha transparency and compresses without discarding any pixel data, which makes it the default choice for screenshots, UI assets, logos, and graphics with sharp edges or text.
Strengths
- Lossless compression — pixels survive every save
- Full alpha-channel transparency
- Universal support in browsers, editors, and operating systems
- Ideal for text, line art, and screenshots
Limitations
- Files are much larger than JPEG or WebP for photographs
- No native animation support (APNG exists but is a separate spec)
- No embedded color-management or metadata richness compared to TIFF
What is JPG? (JPEG (Joint Photographic Experts Group))
JPG (JPEG) is the most widely used lossy image format, standardized in 1992. It achieves 10:1 or greater compression on photographs by discarding detail the human eye barely notices, which is why virtually every camera and phone shoots JPEG by default.
Strengths
- Very small files for photographic content
- Supported by literally every device, browser, and app
- Adjustable quality/size trade-off
- Fast to decode on any hardware
Limitations
- Lossy — quality degrades with every re-save
- No transparency support
- Visible artifacts around text and sharp edges
PNG to JPG conversion: your questions answered
What happens to transparency when I convert PNG to JPG?
JPG has no alpha channel, so transparent pixels are flattened onto a solid background — white in most converters. If your PNG is a logo or cut-out graphic, keep it as PNG or convert to WebP instead.
How much smaller will the JPG be?
For photographic content, a quality-90 JPG is typically 60–80% smaller than the source PNG. Screenshots with large flat areas compress differently; expect 30–60% savings there.
Will I lose image quality converting PNG to JPG?
Yes — JPG is lossy, so some data is permanently discarded. At quality settings of 90 or above the loss is invisible on photos, but text-heavy images and graphics with hard edges may show ringing artifacts. Keep the original PNG as your master copy.
Is it free to convert PNG to JPG with JoltFile?
Yes. JoltFile's free tier covers everyday PNG to JPG conversions with no account and no watermarks. Higher file-size limits and batch processing are planned for the upcoming Pro tier.
Is my PNG file private when I convert it?
Yes. JoltFile is designed around browser-based processing: whenever technically possible your file is converted locally on your own device and never uploaded to a server. Files that do require server processing are encrypted in transit and deleted automatically after conversion.
