PixozipConvert images online — free
Drop in JPG, PNG, WebP, AVIF, HEIC, GIF, TIFF or SVG files, pick the format you want out, and get them back converted. Most converters stop there and hand you a file that is sometimes bigger than what you started with. Here the conversion and the optimization happen in the same pass, so the new format arrives at its smallest sensible size.
No account, no watermark, no email. Up to 20 files at a time, with a before/after preview and a one-click ZIP. Your files are deleted automatically within a day.
Convert your images
Choose an output format, then drop your files. Everything runs on the real Pixozip engine.
Each file keeps its own format and is just made smaller.
Which format should you pick?
The safe modern default. Supported by every current browser and typically 25-35% smaller than JPEG at the same visual quality.
Goes smallest of the four, often 50% under JPEG, at the cost of slower encoding. Best served with a WebP or JPEG fallback.
The universal choice for photographs. Use it when something has to open absolutely everywhere, including old software.
Lossless, with real transparency. Right for logos, icons, screenshots and flat graphics — wasteful for photographs.
Need JPEG XL as well? It is available through the API, where you can also set an exact quality target.
Popular conversions
Each of these has its own page with notes specific to that pair — what survives the conversion, what to watch for, and what size change to expect.
SVG works here too — drop one in and pick a raster format to render it. To keep it a vector and just make it smaller, optimize it as SVG.
Converted and optimized together
One pass does both, so you never have to run the result through a second tool to make it small.
Files do not linger
Originals and results sit in temporary storage and are removed automatically within a day.
The same engine as the API
What you get in the browser is exactly what an API call returns — nothing is downgraded for the free tool.
Questions about converting
Is converting an image the same as compressing it?
No, and here you get both at once. Converting changes the container and codec; compressing reduces the bytes inside it. A file converted by a naive tool can easily come out larger than the original. Every conversion here runs through the same optimizer that powers our API, so the new format arrives at its smallest reasonable size.
Which format should I convert to?
WebP is the safe default for the web: universal support and a large size win over JPEG. AVIF goes smaller still and suits image-heavy pages where you can serve a fallback. Convert to JPG when maximum compatibility matters, and to PNG only when you need lossless output or true transparency.
Will transparency survive the conversion?
It survives into PNG, WebP and AVIF, all of which carry an alpha channel. JPEG has none, so converting a transparent image to JPG flattens it onto a solid background — pick WebP or PNG if the transparency matters.
Can I convert an SVG to PNG or WebP?
Yes. Drop an SVG in and pick a raster format, and the vector is rendered to pixels at the size the document declares. Ask for something larger and it is drawn at a higher resolution rather than upscaled from a small bitmap, so edges stay sharp. Choosing JPG flattens it onto white, since JPEG cannot store transparency.
Can you turn a photo into an SVG?
No. Rasterizing a vector is a straightforward render; tracing pixels back into vector paths is a different problem with no faithful answer, and the results tend to be either enormous or a poor likeness. We would rather not ship something that quietly produces bad output.
Is there a limit, and what happens to my files?
Up to 20 files per batch, 10 MB each, with no account needed. Uploads and results live in temporary storage and are deleted automatically within a day. We never use your images for anything else.
Can I automate this instead of using the browser?
Yes. The same conversion is a single API call, with official SDKs for Node and PHP plus plugins for WordPress, OpenCart and Joomla. Every account starts with 500 free conversions a month.
Converting more than a handful?
The same conversion is one API call, with SDKs and CMS plugins. Every account gets 500 free conversions a month.
