What's the difference between JPG and PNG?
JPG (Joint Photographic Experts Group image) and PNG (Portable Network Graphics) solve different problems: JPG is a lossy compression format built for photos, web images, email attachments, while PNG is a lossless compression format whose strength is screenshots, logos, graphics with transparency. In practice you will meet JPG when dealing with photos, web images, email attachments, and reach for PNG when you need screenshots, logos, graphics with transparency — the table below compares them point by point.
| JPG | PNG | |
|---|---|---|
| Full name | Joint Photographic Experts Group image | Portable Network Graphics |
| Developed by | Joint Photographic Experts Group | PNG Development Group (W3C standard) |
| Released | 1992 | 1996 |
| Compression | Lossy compression | Lossless compression |
| Typical use | photos, web images, email attachments | screenshots, logos, graphics with transparency |
| File extension | .jpg | .png |
| MIME type | image/jpeg | image/png |
Why convert JPG to PNG?
JPG (or JPEG) is a lossy raster image format released in 1992 by the Joint Photographic Experts Group. It compresses photographs into small files by discarding visual detail the eye rarely notices, and is the most widely supported image format on the web, in cameras, and across operating systems. Here is when PNG is the better choice:
- →PNG is lossless — no compression artifacts, ever. Text and sharp edges stay crisp.
- →Full alpha transparency makes PNG the standard for logos and UI assets.
- →It runs in the cloud — 10 free conversions a day with files up to 200 MB (20/day and 500 MB with a free account) — so even a phone or an old laptop converts at full speed.
Before you convert: three quick tips
- ●If your image has a transparent background, pick a target that supports it (PNG, WebP, AVIF); converting to JPG fills transparency with white.
- ●For web use, the modern formats (WebP, AVIF) save the most bandwidth; for maximum compatibility, JPG and PNG remain the safe choices.
- ●Keep your original JPG — conversion never modifies it, and if you later need a different target format, starting from the original always gives the best quality.
PNG conversion settings explained
PNG is a lossless format, so there is no quality slider — the output always preserves complete pixel data. That makes results predictable: the same input always produces the same quality output.
A note on size: lossless file size depends on image complexity. Screenshots and graphics with flat colors compress extremely well; photographic content will come out noticeably larger than lossy formats like JPG or WebP — the fair price of zero loss.
How the conversion works
Filevo converts JPG to PNG with libvips, the high-performance open-source image engine that powers the Sharp library used across the industry. libvips processes images as a stream with a tiny memory footprint, so a typical photo converts in under a second. The work happens on our servers, not your device — a phone or an aging laptop converts just as fast as a workstation.

What is PNG?
PNG (Portable Network Graphics) is a lossless raster image format standardized in 1996 as a patent-free replacement for GIF. It preserves every pixel exactly, supports full alpha transparency, and is the default choice for screenshots, logos, and graphics with sharp edges or text.

JPG to PNG converter FAQ
How do I convert JPG to PNG for free?
Drop your JPG file into the converter at the top of this page, confirm PNG as the target, click Convert, and download the result. It is genuinely free: 10 free conversions a day with files up to 200 MB (20/day and 500 MB with a free account), no watermarks, no software to install, no account required.
Is it safe to convert JPG files online?
Yes. Transfers are TLS-encrypted end to end, and conversion is fully automated — no human ever sees your files. Your uploaded JPG is deleted the moment conversion finishes, and the converted PNG auto-deletes after 24 hours (you can delete it sooner). We never use your files for AI training or share them with anyone.
Will I lose quality converting JPG to PNG?
PNG is lossless and preserves the decoded data exactly. One honest caveat: detail that JPG already discarded cannot be recovered — converting stops any further quality loss, but it cannot restore what is gone. Expect the file to get larger.
How long does JPG to PNG conversion take?
Usually seconds. The conversion itself takes from under a second to a few seconds for images and audio — most of the wait is the upload, which depends on your connection speed. Since processing happens in the cloud, your device stays fast, and you can run several conversions in parallel.
Can I convert JPG to PNG on iPhone or Android?
Yes. Filevo runs entirely in the browser, so it works the same on iPhone, Android, tablets, and computers — no app to install. On mobile, tap Browse Files to pick from your photos or files.
What's the maximum file size?
Anonymous conversions accept files up to 200 MB; a free account raises that to 500 MB. Paid plans go from 1 GB up to 10 GB per file, with higher daily limits and priority queues.
Can I convert multiple files at once?
One file per conversion today — though you can start several conversions in parallel. Batch upload with zip download is on the near-term roadmap.
Does converting change my image dimensions or resolution?
No. Converting JPG to PNG keeps the original pixel dimensions — a 4000×3000 image stays 4000×3000. Only the encoding and the file size change.
Why is my PNG larger than the original file?
PNG is lossless, so it stores every pixel exactly. Converting a compressed photo (like JPG or WebP) to PNG usually increases file size — that is expected and means no quality was lost.
Whether you need screenshots, logos, graphics with transparency or simply a file that works where JPG will not open, the converter above turns JPG into PNG in seconds — free, private, and with nothing to install. Bookmark this page for the next time a JPG file refuses to cooperate.
