convert images
Change an image to JPEG, PNG, WebP or AVIF in this tab. Nothing is sent anywhere, so there is no size limit and no queue.
There is no Google Drive or Dropbox button on purpose: those send the file through a server. Here is what happens instead.
in three steps
- Drop your images in, or choose them. They are read by this page — nothing is uploaded.
- Pick the format. Each one says what it is good for and what it gives up; set the quality if the format has one.
- Convert, and take the files. The log shows the real sizes, and a batch can come down as a single zip.
how it works
Drop one image or fifty. Each one is decoded by your browser, drawn onto a canvas and written back out in the format you choose. Pick the format, set the quality if the format has one, and the tool tells you what each file will be called before you start.
A batch runs one file at a time and reports each one as it finishes. If a file fails — an image this browser cannot read, or a format it cannot write — that row says so and the rest carry on. You can cancel mid-run and keep whatever was already converted.
why doing this locally matters here
Photographs carry more than the picture. A phone writes the time, the camera model and often the exact coordinates into the file, and a screenshot of a document carries whatever was on the screen. Sending that to a converter means handing it to whoever runs the converter, and their retention policy becomes your problem.
Here the pixels never leave the tab, so there is nothing to retain, nothing to leak in a breach and nothing to subpoena. That is also why there is no size limit: the cost of a large file falls on your machine, not on a server someone has to pay for. If you want to strip the camera data as well, remove the metadata before you share the file.
questions
Where does my image go?
Nowhere. The file is read by the page you already loaded, drawn onto a canvas and written back out in the new format, all inside this tab. There is no server behind this site that could receive it. The job log under the tool reports how many network requests the page made while converting — it is zero — and you can confirm that yourself in your browser's network panel.
Which format should I choose?
JPEG for photographs you need everything to open. PNG when you need exact pixels or transparency. WebP when you want a smaller file than JPEG at the same quality and only need it to open in a browser or recent software. AVIF when size matters most and you know the software opening it is recent. Each option on the tool carries the same summary next to it.
Why did my transparent background turn white?
JPEG cannot store transparency, so anything see-through has to become a colour when you convert to it. The tool warns you before you convert and fills with white. Choose PNG, WebP or AVIF to keep the transparency.
Is there a size limit?
Not one imposed by this site. The limit is your device's memory, because the image is decoded in your browser. A photo from any phone or camera is far below that. Very large scans — hundreds of megapixels — can exhaust a tab on a phone, and the file simply fails rather than being uploaded somewhere bigger.
Can it convert HEIC photos from my iPhone?
Only in Safari. HEIC is decoded by the operating system, and Chrome and Firefox on desktop do not do it, so a HEIC dropped there fails with a clear message instead of a broken file. A HEIC decoder that works everywhere is a large download, and shipping one is a separate decision we have not made yet.
Is this really free?
Yes. There is no account, no trial and no paid tier. Advertising pays for the hosting, and since your file never reaches us there is nothing about it to sell.
