What's the difference between PNG and AVIF?
PNG (Portable Network Graphics) and AVIF (AV1 Image File Format) solve different problems: PNG is a lossless compression format built for screenshots, logos, graphics with transparency, while AVIF is a lossy compression format whose strength is next-gen web images, photography portfolios. In practice you will meet PNG when dealing with screenshots, logos, graphics with transparency, and reach for AVIF when you need next-gen web images, photography portfolios — the table below compares them point by point.

Why convert PNG to AVIF?
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. Here is when AVIF is the better choice:
- →AVIF is the most efficient mainstream image format — about half the size of JPG at equal quality.
- →HDR and 10-bit color support make it future-proof for photography.
- →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 PNG — conversion never modifies it, and if you later need a different target format, starting from the original always gives the best quality.
AVIF conversion settings explained
The quality setting (1–100) controls how aggressively AVIF compresses. Filevo defaults to 85 — the golden value for web and everyday sharing: compression artifacts are essentially invisible while files stay around half the size of quality 100.
How to choose: 75–80 for web images where every kilobyte counts; 85 (default) for almost everything; 95+ for print or images you plan to edit further. Note that quality 100 is still not lossless — choose PNG or TIFF as the target if you need true lossless output.
How the conversion works
Filevo converts PNG to AVIF 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.
Why convert PNG to AVIF?
PNG is lossless, which makes it reliable but heavy — especially for photographic content or graphics with smooth gradients. AVIF changes the math: it typically makes files 60–80% smaller than PNG while keeping full transparency. For a website serving logos, illustrations or transparent product shots, that’s a massive bandwidth saving with no visible quality loss at sensible settings. If your PNGs are weighing your pages down, AVIF is the modern answer.
Transparency kept, size slashed
AVIF supports a full alpha channel just like PNG, so transparent areas survive the conversion intact — no white box around your logo. Cleverly, AVIF stores the alpha channel separately from the color data, so compression settings affect the colors while the transparency edges stay sharp. The result is a tiny file that still drops cleanly onto any background, which is exactly what transparent web graphics need.
Lossy AVIF vs your lossless PNG
Be clear on the trade: the dramatic size savings come from AVIF compressing the colors with high-quality lossy encoding, not the byte-for-byte lossless storage PNG uses. For photos, illustrations and gradient-heavy graphics with transparency, the difference is invisible at good quality settings and well worth it. But for pixel-exact assets — icon sets, UI sprites, screenshots with text, sharp pixel art — where a single softened edge matters, keeping the original PNG (or serving AVIF only with a fallback) is the safer call.
Convert PNG to AVIF on any device
On Windows or Mac: drag the PNG straight from Explorer or Finder into the converter above. On iPhone or Android: open this page in your browser, tap Browse Files and pick the PNG — no app required. The AVIF encode runs in the cloud, so you just download a far smaller file with its transparency intact. Remember AVIF needs a modern browser (about 94% support), so use a fallback for production sites.

What is AVIF?
AVIF is an image format released in 2019 by the Alliance for Open Media, built on the AV1 video codec. It achieves roughly 50% smaller files than JPG at the same quality, supports HDR, wide color gamut, and transparency, and is now supported by all major browsers.

PNG to AVIF converter FAQ
How do I convert PNG to AVIF for free?
Drop your PNG file into the converter at the top of this page, confirm AVIF 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 PNG files online?
Yes. Transfers are TLS-encrypted end to end, and conversion is fully automated — no human ever sees your files. Your uploaded PNG is deleted the moment conversion finishes, and the converted AVIF 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 PNG to AVIF?
Your PNG source is lossless, so the output quality depends entirely on the quality setting you pick. The defaults produce results visually or audibly indistinguishable from the original at a fraction of the size.
How long does PNG to AVIF 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 PNG to AVIF 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?
Yes. Drop up to 50 files at once — they roll through the queue automatically. Pick a target format per file or set one per category, then download results individually or grab everything as a single ZIP.
Does converting change my image dimensions or resolution?
No. Converting PNG to AVIF 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.
Does PNG to AVIF keep transparency?
Yes, fully. AVIF supports a complete alpha channel and stores it separately from color, so transparent areas stay sharp while the file shrinks dramatically. Your logo or icon keeps its see-through background — no white box.
How much smaller is AVIF than PNG?
Typically 60–80% smaller, depending on the image. The savings are largest for photographic content and smooth gradients. The size drop comes from lossy color compression, so at good quality settings the result looks the same while weighing a fraction as much.
Should I use AVIF for icons and pixel art?
For pixel-exact assets — icons, UI sprites, screenshots with text, pixel art — where a single softened edge matters, the lossy compression may not be ideal; keep the PNG or serve AVIF only with a fallback. For photos, illustrations and gradient graphics, AVIF is excellent.
Whether you need next-gen web images, photography portfolios or simply a file that works where PNG will not open, the converter above turns PNG into AVIF in seconds — free, private, and with nothing to install. Bookmark this page for the next time a PNG file refuses to cooperate.
