Supports: PNG
PNG is the format you reach for when edges have to stay sharp and backgrounds have to stay transparent — logos, screenshots, UI exports, line art. It is lossless, so it never throws pixels away, but that also makes PNG files heavy for photographic content and unusable in a few places that expect JPG, ICO, or a vector. This converter takes a PNG (or a whole batch of them) and rewrites it as JPG, WebP, GIF, ICO, BMP, TIFF, SVG, or PDF, with the quality, resize, palette, and background-color controls each target actually needs. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after one hour — no sign-up, no watermark, never shared.
Each target format solves a specific problem that PNG itself does not:
<link rel="icon"> for modern browsers.| Your goal | Best output | Why |
|---|---|---|
| Web image that needs transparency | WebP | Keeps the alpha channel, 23-42% smaller than PNG lossless (varies), ~96% browser support |
| Photographic image, no transparency needed | JPG | Far smaller than PNG for photos; transparency is flattened onto a background |
| Favicon or legacy Windows icon | ICO | Bundles 16–256 px sizes in one file for older shortcut and CMS handlers |
| Tiny flat graphic or legacy-only target | GIF | 256-color palette, widely accepted; avoid for photos |
| Uncompressed bitmap for old tooling | BMP | Raw pixels, no decode step; large files |
| Print or archival hand-off | TIFF | Up to 16-bit, lossless, DPI-aware |
| Logo that must scale infinitely | SVG | Vector paths; best for flat, high-contrast art only |
| Document or multi-image hand-off | One portable file that any PDF reader opens |
| Property | PNG | WebP | JPG |
|---|---|---|---|
| Compression | Lossless | Lossy + lossless | Lossy |
| Transparency (alpha) | Yes | Yes | No |
| Color depth | 8 or 16-bit/channel | 8-bit/channel | 8-bit/channel |
| Animation | APNG only | Yes | No |
| Typical size vs PNG | baseline | 23-42% smaller (lossless) | much smaller for photos |
| Browser support | Universal | ~96% (Safari 16+) | Universal |
| Best for | Logos, screenshots, transparency | Modern web images | Photos, universal sharing |
PNG stores transparency in a true alpha channel, so a logo can sit cleanly on any background. JPG and BMP have no alpha channel at all, so every transparent pixel must be replaced with a solid color the moment you convert. That is why this converter exposes a background-color choice for those targets: the default is white, but if your logo will sit on a dark header, set the background to match so you do not get a white halo. If keeping transparency matters more than reaching a JPG-only system, convert to WebP instead — it preserves the alpha channel and is still smaller than the source PNG in most cases. GIF supports a single fully-transparent palette index rather than smooth alpha, so soft, anti-aliased edges turn into hard or fringed edges; for crisp transparency at small sizes, WebP is again the better target.
Because PNG is lossless, the only quality loss in a conversion comes from the target. PNG to PNG, PNG to TIFF, and PNG to lossless WebP are pixel-identical. PNG to JPG and PNG to lossy WebP introduce compression, controlled by the Quality Preset — "Very High (Recommended)" stays visually transparent for almost all images, while lower presets trade visible detail for a smaller file. Resizing happens before encoding, so shrinking a 2000-pixel screenshot to a 600-pixel web asset both reduces the dimensions and the byte size in one step. For GIF, the dominant size lever is the color-palette size rather than a quality slider, since GIF is already limited to 256 colors.
Need the other direction or a different source format? The universal image converter handles 35+ inputs, and the image compressor shrinks a PNG in place without changing its format.
Yes. The JPG format has no alpha channel, so every transparent pixel is flattened onto a solid background the instant you convert — white by default. This converter lets you pick that background color first, which matters when your graphic will sit on a non-white surface and you want to avoid a halo. If you need to keep transparency at a smaller size than PNG, convert to WebP instead.
For almost any PNG headed to a modern website, WebP is the better target. It keeps the alpha channel that JPG destroys, and Lossless WebP is typically 23-42% smaller than the equivalent PNG (the range depends on the source PNG optimizer), with lossy WebP often around 3× smaller than PNG while still supporting transparency. WebP has roughly 96% global browser support (Safari added it in version 16). Choose JPG only for photographic content that does not need transparency, or when a target system explicitly requires JPG.
ICO files bundle several square resolutions in a single file so the operating system can pick the right one. Standard sizes are 16×16, 32×32, 48×48, 64×64, 128×128, and 256×256 pixels. For a website favicon in 2026, MDN actually recommends shipping a PNG through a <link rel="icon"> tag for modern browsers; reach for ICO when you also need to support older Windows shortcut handlers or legacy CMS themes that still expect it.
GIF indexes an image down to a palette of at most 256 colors. A PNG photo or a gradient that contained thousands of colors has to be reduced to fit, which produces visible banding and dithering. GIF also supports only a single fully-transparent palette index rather than smooth alpha, so anti-aliased edges turn hard or fringed. GIF is fine for tiny flat graphics or legacy-only targets; for photos or smooth transparency, convert to WebP instead.
Up to a point. SVG is a vector format, so the conversion traces the raster PNG into paths rather than embedding the pixels. That tracing works well for flat, high-contrast art — a two-color logo, an icon, a simple silhouette — where the edges are clean enough to follow. It works poorly for photographs and detailed images, which have no crisp boundaries to trace and produce a bloated, messy result. Use PNG to SVG for logos and icons you need to scale infinitely, not for photos.
Resizing down (a smaller Resolution Percentage or a smaller custom Width x Height) is clean — you are discarding pixels you no longer need, and the result is sharp. Resizing up cannot invent detail that was never captured, so an enlarged PNG will look soft regardless of the target format. The converter resizes before it encodes, so for a lossy target like JPG or WebP you get the dimension reduction and the compression saving in the same pass.
A typical 1920×1080 UI screenshot exported as a 24-bit PNG (around 1.5–2.5 MB depending on detail) can drop to roughly 150–400 KB as a "Very High" quality WebP while keeping any transparency, and to a similar or slightly smaller JPG once transparency is flattened. Flat graphics with large solid areas compress even harder. Exact numbers depend on how much fine detail and how many distinct colors the image contains, so treat these as a ballpark rather than a guarantee.
Yes. Drop a whole folder of PNG files, pick a single Image File Extension, and every file converts to that target with the same quality and resize settings. The results download individually or as a single ZIP. Because the work runs on our servers, a large batch does not depend on a paid tier or a waiting line.
