Files are removed automatically
Standard server conversions delete uploads when processing ends and remove results 30 minutes later. Other server workflows keep the job's files together until expiry, for example when continued editing, previews or downloads are available. Those files are scheduled for deletion 30 minutes after processing or the most recent request that extends the job. Browser-only tools never upload your files.

Most people arrive here with one specific problem. These are the most common ones, with the tool that solves each and a guide that explains the details.
- An iPhone photo won't open on Windows or in an upload form. iPhones save photos as HEIC. Convert them with HEIC to JPG, or read how to open HEIC photos on Windows.
- A PDF is too big for email or an online form. Compress PDF shrinks scanned and photo-heavy files the most: in our test a 5.9 MB PDF dropped to about 290 KB. This guide explains each level.
- A form asks for a photo under 100 KB. Use the Image Compressor or Resize Image. This guide shows which one to try first.
- You need the audio or the words from a video. MP4 to MP3 saves the soundtrack, and Video to text writes down what is said.
- A video is too large to send. The Video Compressor re-encodes it at up to 720p or 1080p. Our guide lists other ways to send big files.
- Several photos should be one document. JPG to PDF puts each photo on its own A4 page, in the order you add them. Here is how to get it right.
Who makes ConvertKiwi
ConvertKiwi is built and run by Thiago, an independent developer in Florida. Every tool is tried with real files before it goes live, and the guides quote the numbers from those tests. The conversions use open-source software such as FFmpeg, libvips and pdf.js, and there is no paid plan or account. Read how the site works and how your files are handled.
