Why convert images to PNG?
PNG (Portable Network Graphics) is the go-to format whenever quality and transparency matter more than file size. Unlike JPG, PNG uses lossless compression — every pixel is stored exactly as it appears, with no compression artifacts, halos, or colour shifts. This makes it the right choice for logos, screenshots, UI mockups, product images with transparent backgrounds, and any image that will be edited and re-saved. When you receive a JPG, WEBP, or AVIF that needs a transparent cutout, or a BMP that needs to be web-compatible, converting to PNG gives you a universally supported, lossless result.
Supported input formats
| Format | Common source | Key reason to convert to PNG |
|---|---|---|
| JPG | Photos, camera output, social downloads | Stop lossy re-compression cycles; enable editing without quality loss |
| WEBP | Web images, Chrome downloads | Compatibility with apps and tools that don't support WEBP |
| AVIF | Next-gen web images, modern cameras | Compatibility — AVIF is poorly supported outside modern browsers |
| GIF | Memes, simple graphics | Remove 256-colour limit; get full colour depth as a still image |
| BMP | Windows screenshots, legacy software | Reduce file size while keeping lossless quality |
| SVG | Vector icons, illustrations | Rasterise to a pixel-based PNG for use in apps that don't render SVG |
For iPhone HEIC photos, use our HEIC to JPG converter first — HEIC requires a specialist decoder. If you then need PNG output, convert the resulting JPG here.
How to convert any image to PNG
- Drop your files — drag onto the upload zone, click to browse, or paste from clipboard. Mix formats freely; up to 30 files at once.
- Click Convert — all files convert in parallel in your browser using the Canvas API. Nothing is sent to a server.
- Download — grab files individually, or download all at once as a ZIP.
PNG is lossless, so there is no quality slider — what goes in comes out exactly, compressed as efficiently as possible without any quality trade-off.
PNG vs JPG: when to use each
The choice between PNG and JPG comes down to content type and use case:
| PNG | JPG |
|---|---|
| Logos, icons, UI elements | Photographs |
| Screenshots with text | Social media photo posts |
| Images requiring transparency | Email photo attachments |
| Images you'll edit and re-save | Web page hero images |
| Pixel-perfect accuracy required | Camera roll exports |
If the image is a photograph destined for the web, JPG (or WEBP) will be much smaller with no visible quality difference. If it's a logo, diagram, screenshot, or anything with a transparent background, PNG is almost always the better choice.
Converting JPG to PNG
The most common reason to convert JPG to PNG is editing: JPG uses lossy compression, and every time a JPG is re-saved, another round of compression degrades the image slightly. Working in PNG stops this cycle — edits and re-saves never add new artefacts. The converted PNG captures the JPG exactly as it currently looks, including any compression artefacts already present. You cannot recover quality that was lost when the JPG was first created. But from that baseline forward, the PNG will remain perfect through any number of edits.
Another reason is sharp edges: JPG creates visible halos and ringing around text, logos, and fine lines. If a JPG logo looks soft, converting to PNG and then re-creating the logo at higher resolution — or using the original SVG — will look much better.
Converting WEBP and AVIF to PNG
WEBP and AVIF are modern, efficient formats built for the web. They achieve smaller files than PNG through lossy or lossless compression, and both support transparency. However, support outside browsers is still uneven — many image editors, CMS platforms, email clients, and design tools do not handle them. Converting to PNG gives you a file that works everywhere. WEBP and AVIF transparency is fully preserved in the PNG output, so logos and cutout images convert cleanly without any background changes.
Converting GIF to PNG
GIF is limited to 256 colours per frame, which causes visible colour banding on photographs and gradients. Converting a static GIF to PNG removes that limitation — the PNG stores full 24-bit colour (16 million colours) plus an 8-bit alpha channel. The result is a visually cleaner image at a comparable or smaller file size. For animated GIFs, only the first frame is captured; PNG cannot store animation. Use our GIF Compressor if you need to keep the animation.
Converting BMP to PNG
BMP is completely uncompressed — a 1920×1080 screenshot is around 6 MB. PNG applies lossless compression to the same pixel data and typically reduces the file to 500 KB–2 MB with no quality loss at all. BMP files appear most often as output from older Windows software, some scanners, and legacy screen capture tools. PNG is a direct upgrade: same quality, much smaller, and supported everywhere BMP is supported — and then some.
Transparency and alpha channel
PNG was designed with transparency in mind. It supports a full 8-bit alpha channel, meaning each pixel can be anywhere from fully opaque to fully transparent, with 254 levels of semi-transparency in between. WEBP, AVIF, GIF (1-bit transparency), and SVG transparency are all preserved when converting to PNG. JPG and BMP have no alpha channel, so their PNG conversions are fully opaque — there is no transparency to carry over. If you need a transparent background for a JPG photo, you will need to remove the background with a dedicated tool after converting.
Batch converting images to PNG
Drop up to 30 files — mix JPG, WEBP, AVIF, GIF, BMP, and SVG freely in a single batch. All files convert in parallel. Download individually or grab a single ZIP with every converted PNG. The ZIP preserves the original filenames with the extension changed to .png. For larger batches, split into groups of 30.
Privacy
All conversion happens locally in your browser using the Canvas API. No file data is transmitted to any server. You can disconnect from the internet after loading the page and the converter will still work.
