What is PNG?
PNG is a lossless raster format with full transparency. It preserves every pixel exactly but produces large files, especially for photographic content where lossless precision is unnecessary.
What is JPG?
JPG is a lossy raster format tuned for photographs. Its DCT-based compression shrinks files dramatically with minimal visible quality loss, making it the universal standard for web photos and email.

When to convert PNG to JPG
Email attachments
Most email providers limit attachments to 25MB. Convert PNG photos to JPG to fit several in one message.
Faster web pages
Replacing PNG photos with JPG can cut page weight by 80% — a major Core Web Vitals win.
Social media uploads
Instagram, Facebook, and X recompress everything to JPG anyway. Pre-converting saves upload time and gives you control over quality.
Cloud storage savings
Free tiers of iCloud, Drive, and Dropbox fill up fast. JPG keeps photo libraries small without visible quality loss.
Bulk photo sharing
Sending holiday photos? JPG keeps the gallery under download limits on Telegram, WhatsApp, and AirDrop.
Print-on-demand
Most print labs accept JPG up to 20MB. Convert big PNG exports down to size before uploading.
Pro tips for the best result
- Don't convert PNG screenshots of text or UI to JPG — sharp edges will get visible halos. Keep them as PNG.
- For photos with transparency you want to keep, convert to WebP instead — it supports alpha and is even smaller than JPG.
- If you'll edit the image later, keep a PNG master and only export JPG copies for sharing.
- After converting, run the JPG through the compressor for an extra size cut with no visible loss.
- Avoid repeatedly opening and saving a JPG — each round-trip drops quality.

Frequently asked questions
How do I convert a PNG to JPG?
Drop your PNG into the converter above. Pixnova flattens transparency onto white and saves a JPG — instantly, in your browser, with no watermark.
How much smaller will the JPG be?
For photos, expect 60-90% smaller. For flat color, screenshots, or text, expect 0-30% smaller — and you may see compression artifacts. Use JPG for photos, keep PNG for graphics with text or sharp edges.
What happens to transparency?
JPG has no transparency, so transparent pixels are flattened onto a solid white background during conversion. If you need transparency, keep the file as PNG or convert to WebP instead.
Is PNG to JPG lossy?
Yes. JPG uses lossy compression — some detail is discarded to shrink the file. The quality is usually indistinguishable from the original for photos at standard quality settings.
Can I bulk convert PNG to JPG?
The tool processes one image at a time today. Each conversion is instant though, so a batch of dozens takes under a minute.
Will image quality drop noticeably?
For photos, no — JPG was designed for natural images. For UI screenshots, text overlays, and logos, JPG can introduce halos around sharp edges. Keep those as PNG or WebP.
Are my images uploaded?
Never. The conversion runs entirely in your browser. Pixnova has no upload server.
