    Your files are processed by your own browser and never sent to a server. You can check: open your browser's network tab, convert a file, and you will not see an upload. The site also works with your connection turned off once the page has loaded.

    How it works

    1. Drop in any images you like, they do not all have to be the same format.
    2. Choose the format you want out.
    3. If you are converting something transparent to JPG, pick the colour that fills the transparency.
    4. Download individually or all at once.

    About this tool

    Convert between image formats without uploading anything. It reads almost anything a browser can display, HEIC from an iPhone, AVIF and WebP from the web, PNG, JPG, GIF, BMP, SVG and even Windows ICO files, and writes the three formats a browser can produce: JPG, PNG and WebP. Mix formats freely in one batch. When the target cannot store transparency you choose what colour goes behind it, rather than having black silently appear the way most software does.

    What can it read, and what can it write?

    It reads HEIC, PNG, JPG, WebP, AVIF, GIF, BMP, SVG, ICO, and writes JPG, PNG, WebP, AVIF.

    That asymmetry is real. A browser decodes almost any image format ever shipped, because it has to display the web, but it only writes JPG, PNG and WebP itself. AVIF is here because we ship an encoder for it: about three megabytes of WebAssembly, fetched to your device only if you pick AVIF, and still nothing leaves your machine. A site offering to write TIFF is doing it on a server, with your file.

    Which format should I pick?

    • JPG: The safest choice: every device, upload form and printer accepts it.
    • PNG: Lossless and keeps transparency, at the cost of much larger photographs.
    • WebP: Smaller than JPG at the same visible quality, and keeps transparency.
    • AVIF: The smallest of the four, often half a JPG. We ship the encoder, so it costs a one-off download.

    Converting a specific format?

    Each of these has its own page with notes on that particular conversion:

    Privacy

    Your files are never uploaded

    Every conversion happens inside your browser, on your own device. No server receives your file, so there is nothing for anyone to store, sell, lose in a breach, or be compelled to hand over. You can check: open your browser’s Network tab and convert something, there is no upload. The site also keeps working with your connection switched off.

    We collect nothing about you

    There are no accounts, no sign-up and no contact form. We do not ask for your name or your email address, and there is no database here holding anything about you.

    What is stored on your device

    Only preferences, such as the output format you last chose. That stays in your browser, is readable only by this site, and is removed if you clear site data.

    Hosting

    The site is served by Cloudflare Pages, which processes the technical information every browser sends with a request, an IP address and user agent, to serve pages and block abuse. That applies to page requests only. Your files are never part of a request.

    Analytics and advertising

    There is no analytics. The site carries advertising from Google AdSense to cover the cost of the domain. Google may set cookies or read a device identifier to choose and measure those ads, and you can review or change what it does at myadcenter.google.com and policies.google.com/technologies/ads. Advertising can never see your files, because your files never leave your device: the ad is a separate part of the page with no access to what you convert.

    Your choice about advertising

    If you are in the European Economic Area, the United Kingdom or Switzerland, you are asked before anything is stored on your device for advertising, and nothing is set until you answer. The message has three buttons and refusing is one of them, on the first screen, in one click, exactly like accepting. Refusing does not put the tools behind a wall and does not remove the advertising; it means the ads you see are chosen without a profile of you. You can change your answer whenever you like using the button at the end of this page, or by clearing this site’s data, which makes the message appear again. What Google does across all sites can be reviewed at myadcenter.google.com. None of this touches your files, which never leave your device to be seen by anyone, consenting or not.

    Getting in touch

    Write to leniv.tech@gmail.com. That address reaches one person. There is no support desk, no ticketing system and no newsletter to be added to, and your message is not stored anywhere other than that inbox.

    Terms

    Free to use

    For personal and commercial work alike, with no account and no watermark. Please do not try to disrupt the site or interfere with how it works for other people.

    Your files stay yours

    They never reach us, so we claim no rights over them and hold no copy of them.

    No warranty

    The tools are provided as they are. Conversion can fail on unusual or damaged files, and converting between formats can lose quality or detail, compressing a PDF, for instance, turns its text into part of an image. Keep your originals, and do not rely on this as the only copy of anything that matters. We are not liable for any loss arising from using the site.
