Klarfile

PDF and image tools that never upload your files.

Merge, reorder, sign, convert, shrink and compare your PDFs; compress, resize and crop your photos. It all happens in this tab: your files are sent nowhere, because there is nowhere to send them.

The problem is not the PDF. It is the upload.

Online PDF services all ask for the same thing: your documents. A contract, a payslip, a medical file, a legal brief, uploaded to a third party, processed on its servers, “deleted within an hour”, allegedly. For many professions that is not a preference, it is a prohibition.

Here there is no word to take on trust

The work is done by your own processor. The only file that moves is the one you save, from the memory of the tab to your disk. Cut your network connection once the page has loaded: everything keeps working.

The tools

Organize

  • Merge PDFscommon

    Several files, one document, in the order you decide.

  • Organize pages

    Reorder, rotate, delete, duplicate: the whole plan.

  • Extract pages

    Pick pages, take them out into a document of their own.

  • Delete pages

    Remove pages while looking at them, and they do not survive under the file you get.

  • Rotate pages

    An upside-down scan set straight: one page, or the whole document.

  • Split a PDF

    One document into several files: one per page, or in even slices.

  • Crop a PDF

    Take the margins off a scan: draw the frame once, it applies to every page.

  • Insert blank pages

    A divider between exhibits, a page for notes, a double-sided print that falls right.

Convert

  • Images to PDFcommon

    Photos and scans become the pages of a single PDF.

  • PDF to imagescommon

    Every page as a PNG or a JPEG, in an archive past one page.

  • Extract the text

    All the text of a PDF in a .txt file, page by page.

  • Extract the images

    The photos and scans that are INSIDE the PDF, at their original size.

Edit

  • Edit a PDF

    Text, signature, stamp, and the pen gestures: highlight, box, annotate.

  • Fill in a form

    Type into the boxes of an official form, and save a sheet that is filled in for good.

  • Number the pages

    Continuous pagination, even on a bundle made of four files.

  • Watermark

    “COPY”, “CONFIDENTIAL”, diagonally or tiled across the page.

  • Overlay two PDFs

    A letterhead, a drawing frame, a stamp: laid over every page.

  • Sign a PDF

    Place your signature, your initials, a date, where you can see them.

  • Normalize the page size

    A bundle made of exhibits of every size, brought back to A4.

  • Booklet and pages per sheet

    A brochure to fold and staple, or two pages per sheet to reread without wasting paper.

Optimize

  • Shrink a PDFcommon

    Re-encode the images so the document fits in an email.

  • Clean the metadata

    Remove the author, the software, the dates, and the active content with them.

Check

  • Redact a PDF

    Make a passage disappear: really, not under a black rectangle.

  • Inspect a PDF

    What your file says about itself, earlier versions included.

  • Compare two PDFs

    Two versions of a contract, and the words that changed between them.

  • Extract the attachments

    A PDF can carry whole files: see which ones, and take them out.

Images

  • Compress an image

    A photo too heavy for a web form, made lighter without leaving the tab.

  • Resize an image

    “1600 pixels maximum”, keeping the proportions, without distortion.

  • Crop an image

    Draw the frame you want to keep, and the rest is really removed.

  • Convert an image

    Between JPEG, PNG and WebP, and we say what you lose on the way.

  • Rotate an image

    A photo taken sideways set straight, for good, not by metadata.

  • Watermark an image

    “PROOF”, “COPY”: laid on the photo, exactly where you want it.

  • Inspect a photo

    What your photo says about you, starting with where it was taken.

  • Clean an image

    Remove the GPS position and the EXIF, without touching a single pixel.

  • Redact an image

    Black out a face, a number plate, a bank account, with nothing left in the file.

  • Grayscale and contrast

    A photo of a document, too grey to read, made legible and far lighter.

  • Contact sheet

    Twenty photos on one A4 sheet: the appendix people actually look at.

What they all have in common

Nothing is uploaded: your documents are opened, transformed and saved by your browser. The file you get is always rebuilt page by page, never written on top of the old one: what you removed is really gone. How to check it in thirty seconds.

And if you would rather depend on no website at all

Klarfile can be copied onto your own server, your file share or a USB stick, and it works with no access to the internet at all. Klarfile on your intranet.
