    How to convert PDF to AVIF

    1. Drop your PDF files onto the box above, or paste them with Ctrl+V.
    2. Pick a quality. Around 90% is indistinguishable from the original for most images.
    3. Give a page range if you only want part of the file, or leave it blank for all of it.
    4. Your browser does the work on your own machine.
    5. Save each file from its tile, or take them all at once.

    What changes, and what does not

    Detail is thrown away for the first time

    PDF keeps every pixel exactly. AVIF does not, and that is the point of it: the file gets far smaller because detail your eye is worst at noticing is discarded. Keep the original if you may need to edit it again.

    About PDF

    A fixed page description. It records where every glyph and line sits, which is why it looks identical everywhere and why pulling structure back out of it is hard.

    About AVIF

    The smallest of the four, often half a JPG. We ship the encoder, so it costs a one-off download.

    Worth knowing: Needs a browser released in the last few years to decode.

    What do I get back?

    One AVIF per page. A single page comes back as one image; several come back as a zip, because browsers throttle a burst of downloads triggered by one click. A PDF page has no resolution of its own, so you choose one: 144 DPI is right for reading on screen, 216 for printing or zooming in.

    Other conversions

    PDF also converts to JPG, PNG, WebP, Text and Word.

    AVIF also comes from HEIC, PNG, JPG, WebP and GIF.

    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.
