Everyday file formats

SwiftFormats covers common image, font, PDF, and CSS unit tasks that web teams handle during publishing and QA.

Local processing

Most conversions run directly in your browser, so files stay on your device instead of being uploaded to a remote queue.

Choose a converter by the result you need

SwiftFormats separates broad conversion tasks from fixed-format tools. Use the homepage when you want to choose an output after upload, or open a dedicated page when the input and result are already known.

What runs in the browser

Image, PDF and font tools use browser APIs or downloaded processing modules. The selected file remains on your device during conversion. Large files still depend on available memory, browser limits and format support.

How to verify a result

Open the downloaded file before removing the original. Check image transparency and dimensions, PDF page order, document layout or font rendering according to the type of conversion you performed.

Frequently Asked Questions

Does the homepage upload my files?

No. Supported conversions are performed locally by the browser. Normal site, hosting and analytics requests do not contain the file selected in the converter.

Which tasks are available from the homepage?

The homepage can route common image, PDF and font inputs to compatible outputs. Dedicated GIF, video, DOCX and CSS tools are linked in the tools directory.

Why does a dedicated converter lock the formats?

A fixed-format page prevents accidental output changes and gives instructions specific to that conversion. Use the image or font converter hub when you need a different result.

What should I do if a file is rejected?

Check the actual file type and the limit shown next to the upload area. Encrypted, damaged or unusually large files may require a desktop application.
