How to choose File Converter tools
Some handle a broad range of file types in one place, while others focus on a specific job like converting PDFs or changing image formats. The clearest way to choose is by what you are converting and how large your files are.
Zamzar is the only tool here with no free plan; it bills from $7 per week and supports 1100+ formats including batch video. Convertio and CloudConvert both have free tiers and cover PDF Conversion alongside general file work, with Convertio capping free uploads at 100 MB. Online Audio Converter and FreeConvert Audio Converter are free to start and built around audio, while PDFTables is built specifically for pulling tables out of PDFs.
How many formats the tool covers
Zamzar supports 1100+ formats and handles audio, video, documents, and images in one place. It is the only tool here that requires payment from the first use, starting at $7 per week. Convertio and CloudConvert each cover 200 to 300+ formats and both offer a free starting plan. Online Audio Converter supports 300+ formats but focuses on audio and video files. If your work stays within audio, FreeConvert Audio Converter covers 450+ audio formats and is free to start.
What the free plan actually allows
Most tools here let you start without paying, but the limits vary. Convertio's free plan caps each file at 100 MB. FreeConvert Audio Converter allows files up to 1 GB on its free plan but limits how many minutes of conversion you get each day. CloudConvert gives free conversions each month but unused credits do not carry over. PDFTables sells credits in one-time packages starting at $50 for 1,000 credits, and those credits expire after one year. Zamzar has no free plan at all.
Whether the tool fits one job or many
If you need to convert PDFs specifically, Convertio and CloudConvert both handle PDF Conversion alongside other formats. PDFTables is built only for turning PDF tables into Excel, CSV, XML, or HTML, and offers an API for large batches. For batch video work, Zamzar and CloudConvert are the two tools here that support it. Convertio also covers image format changes and basic PDF organisation. Online Audio Converter adds tag editing on top of format conversion, which the audio-only tools here do not all offer.
