There's a specific kind of frustration that happens on mobile.
You get an email with a PDF attachment. You need to sign it, compress it, or pull one page out of it — and instead of doing that, you spend three minutes scrolling through app store results, downloading something with a suspicious number of permissions, doing the thing, and then wondering if your file just got uploaded somewhere sketchy.
It doesn't have to work that way.
Everything on FileConvy runs in your browser. No app, no account, no installation. That's true on desktop, and it's equally true on your phone. You open the tool, upload the file, download the result. Same experience, smaller screen.
Here's what that actually looks like for the tasks people most often need to do on the go.
The PDF you need to edit — but can't
Someone sends you a contract as a PDF. You need to change a date, fix a typo, or fill in a field. On desktop you'd open it in Word. On mobile, most people give up and wait until they're at a computer.
The move here is PDF to Word. Upload the PDF, download a DOCX. Open it in Google Docs on your phone — which handles DOCX files fine — make your change, export back to PDF. Done without touching a laptop.
It's a two-step workaround, but it takes about two minutes and produces a properly editable document rather than a flattened image someone drew boxes on.
The file that's too big to send
This one happens constantly. You scan a document with your phone camera, the resulting PDF is 18MB, and the email service or WhatsApp won't take it.
Compress PDF brings most files down to a fraction of their size without any visible quality loss. For scanned documents specifically — which are usually just large images — the compression is particularly effective. A 20MB scan routinely comes out under 2MB.
Same tool works for images if the file that's too big is a JPG or PNG rather than a PDF — Compress Image handles that side of things.
The document you need to sign without printing
The standard mobile workflow for signing a PDF involves printing it, signing it with a pen, scanning it, and emailing it back. That workflow requires a printer, which many people don't have access to at all, let alone when they're away from the office.
If you need to sign and someone sends you a PDF form, the more practical path on mobile is: convert it to Word with PDF to Word, open it in Google Docs, type your name in the signature field, export as PDF, send it back.
Not elegant, but it works on any smartphone, takes three minutes, and doesn't require a printer or a separate app.
Combining documents from your phone
You've got three PDF files in different locations — one in your email, one saved to your phone, one someone just sent you on WhatsApp. You need them as one document.
Merge PDF takes multiple files, lets you order them how you want, and outputs one combined PDF. Uploading from a phone works the same as desktop — tap the upload zone, use the file picker to navigate to wherever the files live on your device.
If you're combining more than just PDFs — say a Word document, a couple of images, and a PDF — Advanced Merge handles mixed file types and generates a table of contents automatically.
Extracting a page from a large document
You've received a 40-page report. You need page 12. Sending the whole thing to someone is annoying; they don't need the other 39 pages.
Split PDF lets you extract individual pages or page ranges. On mobile, the interface is the same — upload, choose which pages, download. Useful both for extracting what you need and for stripping out pages you don't want to share.
Protecting a file before sending it
You're about to share a document with sensitive information — financial details, personal data, a confidential proposal — and you want to make sure only the right person can open it.
Protect PDF adds AES-256 password encryption in a few taps. The recipient enters the password to open it; without that, the file is unreadable. Unlock PDF goes the other direction if you need to remove a password from a file you own.
The scanned document nobody can search
A lot of documents people receive on mobile are scanned — older contracts, medical forms, government letters that got photocopied six times. These look like PDFs but the text inside is actually an image. You can't select it, search it, or copy from it.
OCR PDF converts those image-based files into real searchable documents. The visual appearance of the document doesn't change — it still looks like the scan — but the text underneath becomes real and selectable. Useful if you need to find something specific in a long scanned document or want to copy a clause from a contract.
Marking something confidential before sharing
You're sending out a draft proposal or an early version of something and want to make it visually clear it's not the final version.
Watermark PDF stamps every page with whatever text you choose — DRAFT, CONFIDENTIAL, DO NOT COPY, your company name — at whatever opacity and angle you set. Works fine from a phone. Takes about thirty seconds.
A few practical mobile tips
Use the browser's "Add to Home Screen" — on both iOS and Android, you can save fileconvy.com to your home screen. It opens like an app but it's just a browser shortcut. Faster than searching for it every time.
Files from WhatsApp work fine — when you tap the upload zone, your phone's file picker shows files from WhatsApp downloads, Google Drive, iCloud, local storage, and email attachments. You don't need to save a file to a specific place first.
Portrait mode is fine — the tools are designed to be usable on a phone screen. You don't need to rotate to landscape or zoom out.
Downloads go to your Downloads folder — on Android, processed files go to the Downloads folder automatically. On iOS, you'll get a Share Sheet prompt asking where to save — Files app, save to iCloud, share via AirDrop, etc.
What you actually need on mobile
The honest answer is: not much. Most PDF tasks that come up when you're away from a desk are one of about six things — convert, compress, merge, split, protect, or sign. All of those are doable from your phone at fileconvy.com without installing anything or creating an account.
The tools that are available:
- PDF to Word — convert to editable format
- Word to PDF — convert back when you're done editing
- Compress PDF — shrink file size for sharing
- Merge PDF — combine multiple files
- Split PDF — extract specific pages
- Protect PDF — add password encryption
- Unlock PDF — remove password from files you own
- Watermark PDF — stamp DRAFT or CONFIDENTIAL
- OCR PDF — make scanned PDFs searchable
- Compress Image — reduce image file size
- Remove Background — AI background removal from images
No app required. No account. Works on the phone you already have.
