Meet Forma—your AI-powered PDF editor that lets you fill, sign, scan, and edit documents. Contracts to sign, forms to fill, files to convert—and no laptop in sight. With Forma, all you need is your phone: edit text, fill out forms, add your signature, scan paper, and convert between formats without disrupting the layout. When a document needs more than editing—a summary, a rewrite, a draft from scratch—the built-in AI assistant will take care of that too. From the creators of iScanner, trusted by 145M+ users. With Forma, you get: • A clean interface that keeps PDF work intuitive. • A built-in scanner with OCR that turns paper into searchable, editable files. • An AI assistant that summarizes, catches mistakes, and generates content. • Secure cloud storage synced across iPhone, iPad, and web. Here's what that looks like: EDIT PDFs WITHOUT LOSING THE LAYOUT Need to update a figure in a proposal or fix a heading before a deadline? Tap any text to edit it—Forma auto-matches fonts so the document looks untouched. You can also highlight sections, add notes, insert images, and split or merge files. VIBE EDIT PDFs WITH A TEXT OR VOICE PROMPT Instead of manually editing PDFs, let the app do the work. Tell Vibe Edit what you want to change by typing a message or recording a voice command, and get your updated PDF right away. FILL & SIGN FORMS WITHOUT PRINTING Tax form, lease, job application—complete any form right in the app. With autofill, you can speed through repetitive fields. Draw or type your electronic signature once, save it, and apply it whenever you need. TURN PAPER DOCS INTO FILES Not every document starts digital. Unlike most PDF editors, Forma has a full scanner built in—point your camera at an agreement, a receipt, or a note, and it becomes a clean, searchable PDF with OCR. CONVERT FILES BETWEEN FORMATS Client needs your PDF as a Word document? Professor wants the assignment in a different format? Convert seamlessly between PDF, Word, Excel, PowerPoint, JPG, and TXT in both directions. LET AI DO THE HEAVY LIFTING Long contract before a meeting? Email that needs a different tone? Summarize lengthy documents, rewrite and polish text, or catch grammar and logic mistakes. Plus, generate cover letters, emails, and more with ready-made templates. CREATE AND SEND INVOICES ON THE GO Project done, time to get paid. Add line items, taxes, and terms, then share with a link or export as a PDF—built for freelancers and remote workers who invoice on the go. BUILD A RESUME THAT STANDS OUT Enter your details and career goals—the AI handles layout, formatting, and design. Whether you're a student entering the job market or making a career move, the result is a professional CV ready to send in minutes. KEEP YOUR FILES SAFE AND SYNCED Store documents securely in the cloud and access them across every Apple device. Blur confidential information before sharing, add watermarks to protect your work, and lock folders with a PIN for added peace of mind. Edit, sign, fill, scan, and convert—Forma is the PDF editor that turns your phone into a document workspace. Download it today. FAQ Q: Can I use Forma offline? A: Yes.

Verdict

The call

The clearest difference is rating: Forma at 4.7 against PDF Converter's 4.2. Forma also leads on ratings volume (26K vs 21) and chart position (#100 vs unranked). PDF Converter's advantage is update cadence (weekly vs monthly) and iOS requirement (15.5 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.
