Make your file fit what the form is asking for
Exact pixel size, an exact KB range — including the minimum, which is what actually gets uploads rejected and which almost every other tool ignores. Plus 115 free tools to merge, compress, and convert PDFs, photos, and documents. All in your browser; nothing is ever uploaded.

A maximum-shrink mode re-renders whole pages instead, for when size matters more than selectable text.Sign a PDFDraw or upload a signature image and place it on a page. This adds a visual signature, not a legally-binding cryptographic signature.Bank statement trust checkCheck a digital bank statement PDF for tampering — reconciles the balances, inspects fonts and metadata, and shows the evidence for every finding.

Preserves text, headings, and paragraph structure — not the exact original layout, fonts, images, or tables.PDF → WordConvert a PDF into a real, editable .docx: paragraphs, headings, font sizes, images in place, and simple tables reconstructed from the layout. Everything stays editable. Densely designed layouts come out simplified.View a Word documentPreview a .docx file's headings and paragraph text right in your browser.Mail mergeCombine a plain-text template with {{field}} placeholders and a CSV of data to generate one .docx per row, zipped together.Compress image to exact size (KB)Shrink one or more images down to at or under a target file size in KB — for exam/application portals with strict upload limits ('photo must be under 50KB'), not just a vague quality slider.Compress PDF to exact size (KB)Shrink a PDF to at or under a target file size in KB — for portals with strict upload limits ('form must be under 300KB'). Recompresses the images inside the PDF first, which keeps text selectable; only re-renders pages when the target can't be reached any other way.Passport Size Photo Maker: 35x45mm, 630x810 pxCrop and resize a photo to an exact passport, visa or ID size in mm, inches or pixels, then optionally lay out multiple copies on a print-ready 4x6in sheet. Drag to reposition, zoom to fit.Whiten photo/signature backgroundTurn a light, fairly uniform background into pure white (or transparent) using a brightness cutoff — good for cleaning up a scanned signature or ID photo shot against textured paper. A simple brightness threshold, not AI subject detection, so it works best when the background is clearly lighter than the subject.Fix a photo for an upload formHit an upload form's rules all at once: exact pixel size, a KB range (not just a maximum), and JPEG format.

Frequently asked questions
Is Docexp really free, or is there a catch?
It's free because there is nothing to meter. Every tool runs as JavaScript in your own browser, so there are no servers processing your files and no compute bill to pass on. That is also why there are no daily quotas, size caps, or watermarks — those limits exist on other sites to ration server time Docexp doesn't use.
How do I know my files aren't being uploaded?
Turn off your Wi-Fi. Once a Docexp tool has loaded, it keeps working with the network disconnected — a site that runs with the network off cannot be sending your files anywhere. You can also watch the browser's Network tab while a tool runs: no file data leaves the page.
Why do upload forms keep rejecting my photo?
Usually because the form sets a range, not just a maximum — 'between 20 KB and 50 KB' — and ordinary compressors only shrink. A JPEG cannot be padded upward by compressing harder, so a photo that lands under the form's minimum stays rejected no matter how many times you re-compress it. Docexp's upload fixer targets both ends of the range, plus the exact pixel dimensions.
Do the tools work on a phone?
Yes. Everything runs in the browser, so the same tools work on Android and iPhone with no app to install. On older phones very large files can be slow, because the processing uses your device's own memory rather than a server.
Do I need to create an account?
No. There is no sign-up, no login, and no email capture anywhere on the site. Since your files are never uploaded, an account would have nothing to attach to.
