Convert images, audio, video and PDFs in your browser

Correct. All conversion and compression runs inside your browser using WebAssembly and WebCodecs; no file is sent to this site's server. You can verify this by keeping the Network tab of your browser's developer tools open while processing: no file upload occurs. Processing statistics used to fix bugs (device specs, error types and so on; never the files themselves or their names) are sent to this site's server. You can turn this off with the switch under “Help us improve the service” at the bottom of the page.

There is no limit on the number of uses. The PDF tools accept files of up to 200 MB each (on phones and tablets, 100 MB, or 50 MB for PDF compression), and you can combine up to 500 images into a PDF at a time. The image, audio and video tools process files on your device, so how large a file they can handle depends mainly on your device's memory, CPU and GPU. As a guide, most devices handle images of tens of megabytes, audio of several hours, and video of several gigabytes.

The image and audio tools work in current Chrome, Edge, Safari and Firefox. The video tools rely on the browser's built-in encoders (WebCodecs), so we recommend desktop Chrome, Edge, Safari 17+ or Firefox 130+. If your browser is not supported, the page tells you. Japanese text to speech uses the GPU (WebGPU), so use Chrome or Edge on a PC with a GPU.

Yes. Video conversion uses a lot of memory, though, so long videos are best processed on a desktop. Image conversion and compression run comfortably on phones. Japanese text to speech does not work on iPhone or iPad.

Images are re-encoded, so EXIF metadata such as capture time, GPS location and camera model is not included in the output. This is also a handy way to strip location data before posting to social media.

No. It is free and requires no account. Running costs are covered by ads.

Only statistics that help us fix bugs. What is sent: the tool you used and the settings you chose (output format, quality, etc.), your device specs (GPU, memory, core count), the input format with a rough size (for text to speech: the approximate number of characters and sentences, how many parts the text was generated in, and how long the AI model took to load; for PDFs: the page count range, the numbers of rewrites, deletions, white-outs and redactions, the number of rewritten characters by source (original font or fallback font, the latter as a range) and the fallback typeface, the kinds of reasons why lines cannot be edited, whether editing is restricted, whether a permissions password was entered, whether the PDF is signed or encrypted, and the number of pages turned into images by redaction and the reasons; for PDF page operations and conversion between images and PDF: the numbers of inputs and outputs, of pages rotated, deleted, duplicated or moved, of images inserted as they are, converted, in HEIC format or with corrected orientation, and of pages rendered at a lower resolution (all as ranges), whether the original was updated in place or a new document was created, and whether the original protection was reapplied, form fields were written into the page and bookmarks were added back; for PDF compression, the number of images downsized, not downsized and black-and-white, the number of downsized images whose transparency was also downsized, that stayed lossless or that were converted from CMYK to RGB, and how many times the file was compressed (as ranges), the kinds of reasons images were not downsized, whether the target size was met and the kind of reason it was not met, the range of how much smaller the file got, and whether the original PDF was returned unchanged; for PDF cropping and page numbers, the number of pages cropped, numbered or with their margins reduced (as ranges), how the margins were set, how the pages to crop or number were chosen, the number format and position, and the range of the starting number), how many files succeeded or failed and how long it took, and the error type and details when something fails. The files themselves, file names, text, subtitles or prompts you add to a video, the text to be read aloud, voice descriptions, the pronunciation dictionary and saved voices, the text in PDFs, the text you rewrote or redacted, passwords, font names and the page ranges you enter, and IP addresses are never sent. The data goes only to this site's own server, never to a third-party service. You can turn it off at any time with the switch under "Help us improve the service" at the bottom of each tool page.

Yes. A password-protected PDF opens once you enter its open password. If the author has restricted editing or page changes, you cannot do those things until you enter the permissions password, and if copying and extraction are restricted, you cannot convert the PDF to images until then. This site does not guess passwords, so if you do not know the permissions password, ask the person who created the PDF. When a new PDF is made from a password-protected PDF, it gets the same open password and restrictions as the original.
