How to get the most out of it. Large files need more memory. If a file is slow, close other tabs, or split the job into smaller parts and join the results afterwards. Open the result in the program that will finally use it (a PDF viewer, Word, an upload form) and check fonts, page order and images before you send it on.

It is aimed at everyday paperwork: applications, certificates, invoices, forms and reports that must be in the right format before they can be uploaded, printed or emailed. Results depend on the quality of the file you start with. Scanned or protected documents may need an extra step, and very large files can be limited by the memory of your device.

Worked example

Say you have a file that a website refuses to accept. Open Interactive ASCII & Extended Latin Table Viewer, add the file, adjust the options if you need to, and download the new version. Then upload that one instead and keep the original untouched as a backup.

Tips for best results

Take a moment to read the options before you start, and try the tool with a small sample first. Everything runs in your browser on your own device, so nothing you type or add is uploaded, and closing the tab clears it. If something does not look right, reload the page and try again, or use the report link on this page to tell us what went wrong so we can fix it. If a result still looks wrong, change one value at a time to see which box matters most. Bookmark this page if you will need the tool again.
