PNG vs JPG: When Converting Makes Sense

PNG is lossless and supports transparency — ideal for logos, UI elements, and graphics. But screenshots and photos saved as PNG carry enormous size penalties: a phone screenshot can be 2MB as PNG and 200KB as an indistinguishable JPG. Converting reclaims that waste.

Convert to JPG when the image is photographic, when a form or platform rejects PNG, or when file size matters — email attachments, website uploads, and cloud storage all benefit. Keep PNG when you need transparency or pixel-perfect graphics like charts with thin lines.

The one behavior to know in advance: transparent PNG regions become white in JPG, since the format has no alpha channel. For logos destined for a colored background, that matters; for photos and screenshots, it never comes up.

Frequently Asked Questions

Everything you need to know.

Why convert PNG to JPG?
File size, mostly. Photographic PNGs are often 5–10x larger than an equivalent JPG. Converting slashes upload times, storage use, and page weight with no visible difference for photos.
What happens to PNG transparency in JPG?
JPG doesn't support transparency, so transparent areas are filled with white. If you need the transparency preserved, keep PNG or use WebP instead.
Does PNG to JPG conversion reduce quality?
Technically JPG is lossy, but at the default 95% quality the difference is invisible for photos and screenshots. Fine single-pixel line art is the only content that may show softening.
Can I convert many PNGs at once?
Yes — batch convert up to 50 PNG files in one pass and download everything as a ZIP. No daily limits apply.
Are images uploaded to your server?
No. Conversion uses the Canvas API directly in your browser, so files never leave your device.
