Upload a fillable PDF and complete it in a normal, readable form — text fields, tick boxes, dropdowns and radio buttons are all detected and listed. When you save, your answers are locked into the page so that every PDF viewer displays them, which is the fix for the single most common complaint about PDF forms: you fill one in, email it, and the recipient opens it to find every field empty. Free, no sign-up, no watermark, and nothing is uploaded.
To fill a PDF form free, open it in a browser form filler, complete the fields, and save with the answers flattened into the page. On ihatepdf, upload the PDF and every fillable field — text boxes, tick boxes, dropdowns and radio buttons — is listed for you to complete. Leave the lock option on and your answers are written permanently into the page, which is what stops a completed form arriving at the other end looking blank. Free, no sign-up, no watermark, and the form is never uploaded.
This is the single most common frustration with PDF forms and it has a precise cause. A fillable PDF stores your answers as values attached to interactive field objects, kept separately from the page content that gets drawn. Whether you see those values depends on whether the viewer chooses to render the interactive layer — Acrobat does, many browser previews and mobile mail clients do not, and some print pipelines ignore it too. So you fill in a form, it looks perfect on your screen, you email it, and the recipient opens it to a page of empty boxes. Flattening removes the ambiguity by drawing your answers into the page as ordinary content and discarding the field structure. The result is a document that cannot display differently anywhere, and cannot be accidentally altered by the next person who opens it.
It is worth knowing which you have, because the right tool differs completely. A genuine fillable form contains AcroForm field definitions — click a box and a cursor appears. A flat form is a page with lines and boxes drawn on it and nothing interactive at all, which is what you get from a scan, a photograph, or a document exported for printing. This tool works on the first kind and will tell you plainly when you have the second. For flat forms, the PDF editor is the answer: place text boxes wherever the answers belong, add tick marks where needed, and download. Neither approach requires printing the form and scanning it back, which remains the worst possible workflow and is still remarkably common.
Government, tax, immigration and university forms are the most common fillable PDFs people encounter, and they are also the ones where getting it wrong costs the most time. Three habits help. Complete every field in one sitting and download immediately, because browser state is not a saving mechanism. Always flatten before submitting, since portals and officials frequently view submissions in software that will not render unflattened field values. And keep an unflattened copy for yourself if you expect to reuse the form next year — flattened answers cannot be edited afterwards, so a second unlocked copy saves retyping everything.
Upload the form at ihatepdf.cv/fill-pdf-form. Every fillable field in the document is detected and shown as a normal form for you to complete, then you download the finished PDF. There is no sign-up, no watermark and no upload — the form is filled on your own device.
Because the answers were saved as editable field values rather than as page content, and not every PDF viewer renders those values back — browser previews and phone mail apps are the usual culprits. Flattening fixes it permanently by writing the answers into the page itself. Keep the lock option enabled and this cannot happen.
Many documents look like forms but are flat pages with lines printed on them, which is normal for anything scanned or produced for printing. There are no fields to complete, and the tool will tell you so rather than failing silently. Use the PDF editor instead to place text anywhere you need it.
Yes. Acrobat Reader can fill forms but pushes you towards a paid subscription for anything further, and Acrobat online uploads your document to Adobe. This runs in your browser with no account and no upload, and handles the flattening step that Reader makes awkward.
Only if you turn off the lock option before saving. Leaving it on is recommended for anything you are sending to someone else, because it guarantees the answers display. Turn it off when the form is a working draft that someone else still needs to complete.
Yes, but as a separate step — fill the fields here, then open the result in the Sign PDF tool to draw, type or upload your signature and place it on the page.
No. Reading the fields, filling them and saving all happen inside your browser. Forms usually contain exactly the information you would least want on someone else's server — names, addresses, dates of birth, account numbers, medical details.
Yes, in any modern mobile browser with nothing to install. The fields are rendered as a normal mobile form, which is often easier to complete than pinching and zooming around the PDF itself.
