About JPEG
JPEG is the standard lossy image format, named after the Joint Photographic Experts Group that published it in 1992. It shrinks photos to a fraction of their raw size by discarding fine detail.
Photos from cameras and phones, images on the web and email attachments; every device and app opens it.
JPEG has no transparency, stores 8 bits per colour channel, and loses a little more quality every time it is saved again.
Convert JPEG to PNG online free, no account required — PNG is a lossless image format with transparency.
Change JPEG to PNG without losing quality — convert JPEG to PNG free in your browser.
Why does my photo get worse every time I edit and save it as JPG? Each save re-compresses the image and piles new artifacts on the old ones — working from a lossless original and exporting once to JPG avoids the buildup.
About PNG
PNG (Portable Network Graphics) is a lossless image format created in 1996 as a free replacement for GIF. It supports full colour and an alpha channel for transparency.
Screenshots, logos, icons, diagrams and any image with text or sharp edges.
For photos a PNG is several times larger than a JPEG, and plain PNG has no animation (that is APNG).
Why convert an image to PNG? When sharp lines, text and transparency matter more than file size: screenshots and logos stay pixel-perfect.
What changes when you convert JPEG to PNG
- The JPEG picture is re-encoded as PNG at the default quality settings, so it looks close to the original but is not bit-identical.
- JPEG is a lossy format and PNG is not: the PNG keeps the decoded JPEG exactly, but it cannot restore detail the JPEG compression already removed, and the file is usually larger.
Settings you can change
Before you convert JPEG to PNG, you can adjust: Width, Height, Scale fit, Crop position, Never enlarge, Quality, Lossless, Progressive, Remove metadata, Auto-orient from EXIF, Rotate, and Background.
Limits
Each plan sets a maximum file size and a number of conversions per day, and video and audio files also have a maximum length. Guests can convert files up to 100 megabytes and 5 per day; a free account raises this to 500 megabytes and 25 per day; paid plans go up to 100 gigabytes.
Your converted PNG file is kept for 2 hours, then deleted.
JPEG to PNG: questions and answers
Does converting JPEG to PNG reduce quality?
The JPEG picture is re-encoded as PNG at the default quality settings, so it looks close to the original but is not bit-identical. JPEG is a lossy format and PNG is not: the PNG keeps the decoded JPEG exactly, but it cannot restore detail the JPEG compression already removed, and the file is usually larger.
What is the difference between JPEG and PNG?
JPEG is the universal lossy photo format. PNG is a lossless image format with transparency.
Can I change the settings when converting JPEG to PNG?
Before you convert JPEG to PNG, you can adjust: Width, Height, Scale fit, Crop position, Never enlarge, Quality, Lossless, Progressive, Remove metadata, Auto-orient from EXIF, Rotate, and Background.
Do I need an account to convert JPEG to PNG?
No. You can convert JPEG to PNG without an account; signing in raises the file-size and daily limits.
How long is my converted PNG file kept?
The PNG file you convert from JPEG is kept for 2 hours, then deleted automatically.
Does converting JPEG to PNG restore the quality the JPEG lost?
JPEG is a lossy format and PNG is not: the PNG keeps the decoded JPEG exactly, but it cannot restore detail the JPEG compression already removed, and the file is usually larger.
Is the PNG an exact copy of my JPEG?
The JPEG picture is re-encoded as PNG at the default quality settings, so it looks close to the original but is not bit-identical.
