Practical answers to the PDF problems people actually run into — written to be useful first, and to be found second. 43 in the drawer so far, newest at the top.
Tracing is a redrawing, not a recovery. It can only follow edges that are genuinely in your file — so the source image decides the result far more than any setting does. The finest PNG gives the finest SVG.
Read itYou uploaded an SVG, the colour control does nothing, and the icon sits there black. It is almost always one of five things — four of them inside the file, and all five identifiable in under a minute.
Read itEvery PDF carries a hidden record of who made it, with what software, and exactly when. Most of it is in two places, most tools clear only one, and the consequences are more concrete than people expect.
Read itThree tools, one tracing engine, three different answers to the same question about colour. The choice is not about what you are uploading — it is about what the file has to do once it is on your site.
Read itIcon sets give the PNG away and charge for the SVG. For a flat icon that is a solvable problem: trace the PNG back into a vector and it recolours in Elementor exactly like a built-in icon.
Read itCtrl+F finds nothing because your document is a picture of words rather than words. OCR fixes that by adding an invisible text layer — without changing a single pixel of how the scan looks.
Read itSplit, extract and remove sound like the same operation and produce three different results. Working out which one you want takes thirty seconds and saves you doing it twice.
Read itCropping a PDF hides the margins rather than deleting them. That is worth knowing before you use it to cut something out of a document you are about to send.
Read itConverting a .docx to PDF is easy. Getting a PDF that looks exactly like the document did is where it goes wrong, and the reasons are always the same three things.
Read itEvery AI image generator hands you a PNG, and a PNG is not a logo file. Here is why they cannot give you vectors, how to prompt for an image that traces well, and what the result honestly will and will not be.
Read itTyping onto a PDF page is straightforward. Changing words that are already there is a genuinely different problem, and knowing which one you have saves a lot of frustration.
Read itPhotos, screenshots and scans all become a single document the same way — but the choices you make about size and order decide whether the result looks deliberate or thrown together.
Read itA designer sends a .cdr and nothing on your computer will open it. Here is what those formats actually are, what opens them for free, and why no browser-based tool can honestly claim to convert them.
Read itThree different jobs get called the same thing, and picking the wrong one is how people end up with forty files they did not want. Which tool does what.
Read itAn SVG has no resolution, which makes it the best format to keep and an awkward one to hand over. Knowing which situation you are in saves a lot of re-exporting.
Read itSending a deck as a PDF and getting slides back out of one are different problems with different answers. What survives each way, and what does not.
Read itPhotoshop files can be opened, converted and even taken apart layer by layer without owning Photoshop — as long as the file was saved the usual way. Here is what that depends on.
Read itSomeone sent you an Adobe Illustrator file and you do not have Illustrator. There is a straightforward answer, and it works because of something most people never learn about the format.
Read itPDFs are supposed to look the same everywhere. When one doesn't, the cause is almost always fonts — here's how to tell, and how to make it stop.
Read itEditing a PDF means four genuinely different things, and picking the wrong one is why it feels so hard. Here's how to tell which job you actually have.
Read itTurning a spreadsheet into a PDF usually goes wrong in one specific way: the columns spill onto extra pages. Here's why, and the four fixes in the order worth trying.
Read itGet a table out of a PDF and into a spreadsheet you can actually calculate with — in your browser, no upload. Plus how to spot the mistakes a converter makes.
Read itConvert a PDF into an editable Word document in your browser. What carries across, what doesn't, and why every converter that promises a perfect copy is overselling it.
Read itSaving a web page as PDF usually loses the backgrounds, breaks the layout, or cuts a table in half. Here is why, and how to get a clean result.
Read itScanned out of order, or assembled from three files that arrived in the wrong sequence. How to organize PDF pages without rebuilding the document.
Read itMaking a QR code takes seconds. Making one that scans from across a room, in bad light, off a matte poster, takes three decisions.
Read itSomeone sent back a revised contract without tracking the changes. Here is how to compare two PDFs properly instead of reading both side by side and hoping.
Read itCourt filings, contracts and bound reports all expect numbered pages. How to add page numbers to a PDF, and where the numbering usually goes wrong.
Read itDRAFT, CONFIDENTIAL, or your own name across a document. How to add a watermark to a PDF, and an honest account of what it does and does not prevent.
Read itA photograph and a scan are the same capture done differently. Lighting, angle and framing are what separate them — and why your council rejected the last one.
Read itYou turn the page, close the file, and it is sideways again. The difference between rotating the view and rotating the document, and how to save one permanently.
Read itThree formats, three different jobs. Which to use for text, for photographs and for anything official — and why sending the wrong one gets documents rejected.
Read itPDF has two different passwords and they do different jobs. One encrypts the file; the other politely asks. Here is which to use, and how to pick a password worth setting.
Read itMost 'PDF forms' have no form fields at all — they are pictures of forms. Here is how to tell, how to complete either kind on screen, and how to make it look deliberate.
Read itA PDF that refuses to open is usually truncated, mislabelled or locked rather than genuinely corrupt. Work through these checks in order before you give up on the file.
Read itStrip the password from a PDF you can already open, so you stop retyping it. The difference between the two kinds of PDF password, and what to do when you've lost one.
Read itAdd a signature to a PDF in your browser and keep the file private. What counts as a legally valid electronic signature, and when you need a certificate instead.
Read itDrawing a black rectangle over text leaves the text in the file, where anyone can copy it out. How redaction actually works, and how to check your file is clean before you send it.
Read itCombine several PDFs into one document in your browser — no account, no upload, no watermark. Includes how to fix page order, mixed page sizes and files that are too big.
Read itTurn PDF pages into images at a resolution that actually holds up. Which DPI to choose, when PNG is the better format, and how to avoid the blurry results most converters give you.
Read itMost email providers cap attachments at 25 MB. Here's why PDFs get so large, which fix actually works for your file, and how to shrink one without uploading it anywhere.
Read itUploading a PDF to an AI model costs several times more tokens than the same content as plain text — and often gives worse answers. Here's why, and what to do instead.
Read itMost PDF websites upload your document to their servers to process it. Here's what that means for contracts, payslips and ID scans — and how to check before you upload.
