Disclaimer
This page sets out the limits of the tools provided on this site, and the circumstances in which their output should not be relied upon without checking. It should be read together with the terms of use.
Keep your original file
Every tool creates a new document and leaves your source file unchanged. Even so, output from this site should not become your only copy of any document you cannot afford to lose.
File processing can fail in ways nothing detects in advance. A document can be structurally damaged in a manner that opens fine in one reader and not another. Check the result before you delete anything.
Output is not guaranteed to be correct
Format conversion and text recognition are both approximations. The formats involved store content in fundamentally different ways, and converting between them requires the software to infer structure that was never explicitly recorded. That inference is sometimes wrong.
Recognition of scanned text is the sharper risk, because its mistakes look like data rather than like errors. A misread digit in a total or a date carries forward silently into whatever you do next. Verify figures, dates and names against the original before relying on them.
Compression changes the document
Reducing file size here rebuilds each page as an image. That is what makes large reductions possible, and it is why text stops being selectable afterwards and why fine detail softens. The same applies to grayscale conversion.
For a form being uploaded to a portal that is usually an acceptable trade. For an archival copy, or a document somebody will need to search or copy from later, it is not. Choose accordingly, and keep the uncompressed original.
Nothing here is professional advice
The guidance on these pages describes how file formats and the tools behave. It is not legal, financial, medical or other professional advice, and it is written by people who build software rather than practice those professions.
This matters most around signatures, where the question is legal rather than technical. Whether a particular signature satisfies a particular requirement depends on your jurisdiction and your circumstances. Ask somebody qualified in that jurisdiction.
Signatures and passwords do less than people assume
A signature placed by these tools is a visible mark drawn onto the page. It carries no certificate, no timestamp and no tamper detection, and anybody holding the file can extract the image from it. If you were asked for a digitally signed PDF, this is not that.
A password controls who can open a document and nothing beyond that. Someone able to read a file can photograph the screen, and permission settings that purport to restrict printing or copying are conventions that readers are expected to honor, not enforcement.
Availability
The site is offered as it is, with no undertaking that it will be reachable at any given moment. It may be unavailable during maintenance, during a hosting failure, or because a third-party service it depends on is down.
Several tools also need to fetch a processing library the first time you use one. If your connection drops, or a network blocks the content delivery network, the tool will report that it could not start rather than failing silently.
Links to other sites
Where these pages point to external documentation or resources, that is for reference. Those sites are run by other people, their content can change without notice, and nothing there is endorsed or vouched for here.
How this relates to the terms
This page explains the practical limits in plain language. The formal position on warranties and liability is set out in the terms of use, which is the document that governs your use of the site.
Where the two are read together, the terms prevail on questions of legal effect. This page is here so that the limits are understandable before anybody has to read the terms.
Contact
If a tool has produced output you believe is wrong, we would like to know. Include the type of document and what you expected, and we will look into it.
