    How we handle your files

    What we collect from the upload

    Only the file you send, for as long as needed to process and return it. No additional data from the file is extracted, indexed, or sent to any third party.

    Where we process

    Rollin Host's own infrastructure, in international Tier III datacenters (Europe and US). The upload goes through temporary storage (Vercel Blob) with automatic deletion right after processing. We do not use third-party conversion APIs (smallpdf, Adobe, etc.). Processing complies with the LGPD, with safeguards for international data transfer (Art. 33).

    How long we store it

    Only as long as needed to process. The file sits in temporary storage during upload and in server RAM during processing (a few seconds), with automatic deletion right after you download the result. It never goes to backup, and we never log the content.

    What gets logged

    Operational logs without content: call timestamp, IP hash (anonymized), operation name (e.g., "merge"), file size, HTTP response code. Retention: 30 days, for debugging and security. None of your personal metadata goes into these logs.

    Cookies and tracking

    No third-party cookies in this tool. The main site uses first-party cookies for the theme (dark/light) and anonymous Google Analytics only if you consent in the CMP banner. Tool pages work even without accepting any cookies.

    Legal basis (LGPD)

    Processing happens under the basis of performance of a service requested by the data subject (Art. 7, V, of the LGPD). Since you submit the file voluntarily for processing, this is the most direct basis possible — no additional consent needed.

    Your rights

    Since we don't store your content, there is no data to access, correct, or delete after processing. You get the LGPD rights (Art. 18) by default. Questions or requests: dpo@rollinhost.com.br (Rollin Host DPO).

    Backend software

    We use an open-source PDF engine, running in a dedicated container on our infrastructure. Your file never goes through a third-party service.

    How to repair a PDF

    1

    Upload the broken PDF

    Even if the reader says the file is damaged. Up to 25 MB.

    2

    Repair

    Our PDF engine rebuilds the object table and rewrites the file from scratch.

    3

    Download the repaired copy

    Open it in your usual reader. The original on your computer is not changed.

    What it is for

    Interrupted download

    A file cut off at the end (missing %%EOF) is the most common case, and the one that recovers best.

    Email attachment that will not open

    "File is damaged" or "invalid format" messages in Adobe, Chrome or on your phone.

    PDF generated by a buggy system

    Reports and invoices exported by old programs, with a non-standard structure.

    File that breaks other tools

    If compression, splitting or OCR fail, repair first and try again.

    Frequently asked questions

    What does the tool fix?
    Structural problems: broken cross-reference table, missing end of file, misplaced objects, wrong header. The content is re-read and saved into a new, valid PDF.
    What does it not fix?
    Content that is truly lost. If parts of the file were overwritten or never arrived, those pages do not come back. And a file that is not a PDF (just renamed) has nothing to repair.
    How do I know it worked?
    The repaired copy opens in the reader without warnings. If it still errors, the damage is in the content, not the structure; in that case we tell you and nothing is taken from your quota.
    Does it work with a password-protected PDF?
    No: an encrypted file needs the password to be re-read. Remove the password first.
    Does the layout change?
    No. The PDF is rewritten with the same content; fonts, images and pages stay the same. The file size may change slightly.
    Does the file stay on your server?
    The PDF is processed on our server and deleted automatically within 1 day. Nobody on the team opens the file.
    Is there a usage limit?
    Free: 3 operations per day with any PDF tool, files up to 25 MB, just your email. The Pro plan unlocks unlimited use and files up to 100 MB.
