About this app

pdfFiller is a PDF editor for Android that lets you edit, fill, sign and convert PDF documents from any device. pdfFiller works as a complete PDF document management tool — with eSignature, a 1M+ forms library, and cloud storage integrations all in one app.



Edit & Fill PDF Documents

pdfFiller lets you edit any PDF document directly on your Android device. Type anywhere on a PDF page, highlight or blackout text, add images, erase content, and draw on PDF files. You can also create fillable PDF forms with fields, dropdowns, and checkboxes to collect data and signatures online. PDF editing works offline — changes sync automatically once you're back online.



Convert JPG, Photos & Files to PDF

pdfFiller converts JPG images, photos, and files to PDF directly in the app — no extra tools needed. You can upload PDF documents from your device, email, or cloud storage and use the built-in PDF converter to change file formats. Finished PDF documents can be exported by print, email, fax, or sent for signature.



Merge, Split & Rearrange PDF Pages

pdfFiller lets you merge multiple PDF files into a single document, split a large PDF into separate files, and rearrange pages in any order. All PDF organization tools are available inside the app without switching to a separate service.



Sign PDF Documents & Collect eSignatures

pdfFiller lets you sign PDF documents with a legally binding electronic signature in just a few taps. You can send documents for eSignature in a role-based order, collect signatures from multiple recipients, and track document status in real time — no printing required.



Access 1M+ Fillable Forms

pdfFiller gives you access to an online library of over 35 million fillable forms — including tax forms, contracts, and industry-specific templates. You can fill and sign PDF forms directly in the PDF editor without printing.



Connect Cloud Storage & Access Documents Anywhere

pdfFiller connects to Dropbox, Google Drive, and other popular cloud storage services so you can upload and access PDF documents directly. All PDF files are protected with data encryption, password protection, and signer authentication. Your PDF documents are available from any device at any time.

The support team was very responsive, professional, and quick to address my concern. I'll update my review after 5–7 business days once I've confirmed that the refund has been reflected in my account.

When you're 90% through filling a form, it "loses connection" and erases everything you filled out. multiple times. EDIT AFTER RESPONSE: It IS you! Your app should not need constant internet connection for me to continue editing the PDF that is on local storage on my device. Your app is poorly designed, and it provides a terrible user experience, so it is worthless. 0/5 stars.

John, hi again! Sorry if any confusion with how it works. Please note that pdfFiller is cloud-based. Once you upload your doc for editing in the account, it is NOT on your local storage/device, actually. It is edited and stored in real time in a cloud (the local version on your phone will remain unchanged). Hence the necessity in stable Internet.

Doesn't save your progress, forces you to create an account, and can't manage to check a single checkbox without checking an entire row. Can't even save your document without paying for a subscription, so it's not really "free". Genuinely impressive in how terrible it is.

Apologies for so much confusion faced! We never actually claimed to be free app, we do have a free trial period though. Are you using it now? If a checkbox takes entire row, that's how a fillable field was assigned by document owner. If you are the doc owner and you need help with this, please email support@pdffiller.com, we'll be with you ASAP.
