PNG to JPG cuts file size by roughly 60–80% for photos and screenshots, at the cost of transparency: transparent areas become white.
PNG is lossless, which is why a single screenshot can weigh 4 MB. For photographs and UI captures, converting to JPG at quality 90 usually cuts the size by 60–80% with no visible difference.
The one thing you lose is transparency: transparent areas become white. If you need an alpha channel, keep the PNG.

Why convert PNG to JPG?
Much smaller files
A 4 MB screenshot often becomes 400–600 KB.
Faster uploads
Email attachments, chat apps and forms all have size caps.
Universally accepted
Every platform that accepts images accepts JPG.
How to convert PNG → JPG
- Drop PNG files. Batch up to 100 at a time.
- Choose quality. 90 for photos, 80 for screenshots with text.
- Download. Transparent pixels are flattened to white.
Why a screenshot loses 80% of its weight
A PNG screenshot is large because it is lossless: every pixel of every antialiased letter edge is stored exactly. JPEG does not store pixels, it stores an approximation of 8 × 8 blocks, and it discards the high-frequency detail that the eye is least likely to miss. On a photograph that trade is invisible. On text it is not — which is why quality matters more here than anywhere else on this site.
At quality 90 and above, body text stays crisp and the file is a fraction of the PNG. At 75 the edges soften and coloured fringing appears around letters, because JPEG also subsamples chroma: it keeps brightness at full resolution and colour at half. Black text on white survives. Coloured text on a coloured background does not.
Flat interface screenshots compress extremely well in JPEG — often to a tenth of the PNG — because large areas of one colour are cheap to describe. Photographs inside the screenshot are the exception: those are the parts that will show artefacts.
Transparency is flattened, as with every JPEG path: the canvas is filled with white before the image is drawn. A screenshot with a transparent background will come out on white.
If the screenshot looks worse than expected
Almost always quality, and almost always fixable by moving one slider.
| Symptom | What causes it | What to do |
|---|---|---|
| Text has fuzzy edges or colour fringing | Quality below 85, plus chroma subsampling | Re-convert at 90–95; the file is still far smaller than the PNG |
| Transparent areas became white | JPEG has no alpha channel | Expected. Keep PNG if the transparency matters |
| The file barely got smaller | The PNG was mostly flat colour, which was already cheap | Nothing to fix — JPEG cannot improve on an already-efficient image |
| Gradients show bands | 8-bit JPEG cannot hold enough steps for a smooth sky | Raise quality to 95, or keep the PNG |
| A photo inside the screenshot looks blocky | That region is photographic and JPEG is spending its bits on the text | Convert at 95, or crop the photo out separately |
Where the JPG will fit and the PNG would not
The usual reason people convert a screenshot at all is a size cap, not a format rule.
| Destination | Typical cap | Settings that fit |
|---|---|---|
| Email attachment | 25 MB per message | Quality 85 — a full-screen PNG can exceed this on its own |
| WordPress media library | 2 MB by default | Quality 80 for full-page screenshots |
| Chat and messaging | 10–16 MB per image | Quality 85 at full resolution |
| Support tickets and bug reports | Often 5 MB | Quality 90, or crop to the relevant area |
| Slides and documents | No hard cap, but file size matters | Quality 90 keeps text sharp |
For documentation, the better fix is usually cropping rather than compressing: a tight crop at quality 95 beats a full screen at 70.
Questions
What happens to transparent areas?
They become white, because JPG has no alpha channel.
Will text in screenshots stay sharp?
At quality 85–90, yes. Below 80, thin text can show ringing artifacts — use PNG or WebP for text-heavy images instead.
Is the conversion done locally?
Yes, entirely in your browser.
What quality should I use for screenshots?
90 to 95. Text is the most sensitive content for JPEG, and the size difference between 85 and 95 on a flat interface screenshot is small.
Why does my transparent PNG have a white background now?
JPEG cannot store transparency, so the converter fills the canvas with white before drawing the image. Use PNG when the transparency has to survive.
