Why convert PNG to JPG?
PNG uses lossless compression and supports a transparent alpha channel, which makes it ideal for screenshots, logos, and UI exports but leaves photo-style PNGs several times larger than they need to be. JPG (formally JPEG) applies lossy DCT compression tuned for continuous-tone photographs, typically cutting file size 60-80% with visual quality that's hard to tell apart from the original. Converting PNG to JPG trades pixel-perfect fidelity and transparency for a much smaller file that moves faster through email attachment limits, CMS upload quotas, and print submission portals.
Photo-tuned compression
JPG's DCT algorithm excels on photographic content where small, localized quality changes are invisible to the eye. PNG's lossless approach wastes bandwidth on photos — you pay the full file-size cost for detail nobody can see.
Predictable backgrounds
PNG transparency renders differently in different tools — checker patterns, white fills, black fills. JPG forces a single opaque background during conversion, so your image looks identical in every viewer.
Upload and email friendly
Email providers, legacy CMSs, and print-submission portals commonly cap attachments at 10-25 MB. Converting PNG photos to JPG almost always brings them under that limit without visible quality loss.
When PNG to JPG makes sense
Choose JPG when the output is a photograph or photographic composition destined for the web, email, or print.
Photographs where PNG's lossless precision is overkill and wasted bandwidth.
Email attachments or CMS uploads with strict size caps.
Print shops and legacy tools that accept JPG but not PNG.
Client handoffs where a single opaque background is preferable to unpredictable transparency rendering.

What you get
Every conversion here runs on a temporary copy, delivers a ready download, and clears out quickly after you’re done.
- Processes a temporary copy on our servers and deletes it after conversion — your original PNG is never modified.
- JPG output targets quality 85 by default, which matches the threshold most platforms expect for photos.
- Download links stay in this tab only; close it to clear the temporary URL.
- No sign-up or queue — reconvert the same PNG any number of times.
Frequently asked questions
What happens to transparency during PNG to JPG conversion?
JPG has no alpha channel, so transparent PNG regions are flattened onto a solid color (white by default). If your PNG uses transparency for composited effects or cutouts, plan to recomposite in Photoshop or GIMP after converting.
Why is my JPG not as small as I expected?
JPG compression depends heavily on image content. Flat, synthetic graphics (logos, UI, text) don't compress well and sometimes produce JPGs nearly as large as the source PNG. JPG is most efficient on photographic content with smooth color gradients. For graphics and screenshots, WebP or AVIF usually compress much better.
Is there quality loss?
Yes — JPG is lossy. Each encode discards high-frequency detail to hit a smaller file. We use quality 85, widely considered the size/quality sweet spot. You won't see artifacts on a photo at normal viewing distance, but repeated encode cycles will degrade visibly, so always convert from the original PNG rather than from an already-converted JPG.
Should I use .jpg or .jpeg as the extension?
Both refer to the exact same JPEG file format. We output .jpg because that's what most modern tools expect; the three-letter extension is a DOS-era holdover, but it's become the convention.
Will EXIF metadata survive?
The Sharp library preserves EXIF by default when converting from PNG to JPG. PNG-specific text chunks (tEXt/iTXt/zTXt) don't transfer because JPG has no equivalent container. If you want a metadata-free JPG, run the result through our /remove/jpg tool.
