A print shop asked for a vector file? Find out in 30 seconds whether your PDF needs text outlined, a logo traced or a re-export, and fix it free in the browser.
"Can you send that as a vector file?" If a print shop, sign maker, embroidery service or packaging supplier has asked you this, you have probably opened your PDF, looked at it, and wondered what exactly is wrong with it. Usually nothing is wrong with the whole file. One specific thing inside it is not vector, and the shop has learned the hard way that it will cause trouble on press. This guide explains what they mean, how to find the problem in half a minute, and how to fix each case for free in the browser.
Is a PDF already a vector file?
Most of the time, yes. A PDF exported from InDesign, Illustrator, Affinity, Figma or even Word stores text, lines and shapes as mathematical curves. Those scale to a business card or a four metre banner without losing a pixel of sharpness, because there are no pixels. The PDF format itself is not the issue. The issue is what was placed inside the page:
- Live text that depends on fonts. The letters are vector, but they are drawn with a font the print shop may not have, or that was not embedded correctly. If the font is missing, the RIP substitutes another one and your headline reflows.
- Placed raster images. A logo saved as JPG or PNG is a grid of pixels no matter which PDF it sits in. Enlarge it and the edges go soft.
- A flattened or scanned page. Some workflows rasterise the whole page on export. The PDF opens fine, but every page is a single photograph of your design.
When someone asks you to "convert the PDF to a vector file" or "send a vectorized PDF", they are pointing at one of these three. Which one decides the fix.

Two checks, no software to install:
- The zoom test. Open the PDF in any viewer and zoom to 800 percent on a logo, a headline and a photo. Edges that stay perfectly crisp are vector. Edges that turn into staircases are raster.
- The selection test. Drag the cursor over a headline. If the letters highlight, that is live font text. If nothing highlights, the text has either been converted to outlines already or the page is one big image.
If you want a report instead of a visual check, run the file through the PDF Preflight Check. It lists every font that is not embedded, every image under 300 dpi, and whether the text has been outlined, which is exactly the list a prepress department would write on a rejection note.
The same word at 800 percent. Vector curves on the left, a 72 dpi raster on the right. The zoom test shows this in any PDF viewer.
Case 1: the text needs to become curves
This is the most common meaning by far. The shop does not have your fonts, or does not trust that they are embedded, so they ask for text "converted to outlines", "to curves" or "to paths". Every letter is redrawn as an ordinary vector shape. The file then looks identical on any machine, with no fonts involved at all.
Upload the file to Convert PDF Text to Outlines, run it, and download. The tool keeps everything else in the file as it is: images, colour profile, bleed, crop marks and page size are untouched. Only the glyphs change from font references to curves.
Three things to know before you send it off:
- Keep your original. Outlined text cannot be edited as text again. The outlined PDF is a delivery file, not a working file.
- Outlined text is not searchable. Screen readers and search engines no longer see letters, only shapes. For anything that will live on a website or needs to meet accessibility rules, deliver the outlined file to the printer and keep a version with live text for everything else.
- Embedding is sometimes enough. Many shops accept a PDF/X file with all fonts embedded. If yours only asked whether the fonts are "in the file", the Embed Fonts tool solves that without touching the text. If they specifically said outlines or curves, outline it.
Case 2: a logo or illustration needs to become a real vector
You have a JPG or PNG logo, probably downloaded from a website at 300 pixels wide, and the sign maker wants an SVG or a vector PDF. This is vectorisation, also called tracing: software finds the edges in the image and rebuilds the shapes as curves.
The Image to Vector tool does this in the browser and outputs SVG or PDF. It gives the cleanest result on flat artwork: logos, icons, line drawings, lettering, anything with clear edges and a limited number of colours. A few things improve the result noticeably:
- Use the largest, least compressed source you can find. A 2000 pixel PNG traces far better than a 300 pixel JPG with compression artefacts.
- A plain background beats a busy one. The tracer has to decide where the logo ends.
- Check the result at high zoom before sending it. A traced curve that looks fine at 100 percent can have a wobble at the edges that shows on a large sign.
The honest limit: photographs cannot become clean vectors. Tracing a photo produces a posterised illustration, which can be a nice effect but is not what a print shop means. When a shop asks for a photo "in vector", they nearly always need a higher resolution original, not a trace.
Case 3: the whole page is one image
If the selection test highlights nothing and every edge fails the zoom test, your PDF was flattened or scanned. Each page is a single raster. No tool can turn a photograph of a page back into the original text and shapes with print quality.
Your options, in order of how good the result will be:
- Go back to the source. Re-export from the design program with "preserve vectors" or a PDF/X preset. This is a two minute job if you still have the file, and the only option that gives you a true vector result.
- Ask the designer for the original. If the file came from an agency, they have it. Ask for a PDF/X-4 with fonts embedded.
- Trace the parts that matter. If the page is mostly a photo but has a logo that must be sharp, crop the logo out, trace it with Image to Vector, and place the result back in your layout.
Note that OCR does not help here. OCR recognises the words so you can search them, but it does not redraw the letters as curves.
Case 4: you have a vector file, they want a PDF
The reverse request. You have an AI, EPS or SVG, and the recipient's system only accepts PDF. Converting is safe as long as nothing gets rasterised on the way, which is what the Vector to PDF tool is for: curves stay curves, text stays text, and the page size follows the artboard.
PDF, SVG, EPS or AI: which one to send
- PDF is the safe default for anything going to print. Every RIP reads it, it holds colour profiles and bleed, and it can carry both vector and raster content. Ask for a PDF/X-4 spec if the shop has one.
- SVG is the web and cutting plotter format. Sign makers, laser cutters and embroidery digitisers often prefer it because it is pure vector with no page concept.
- EPS is the format older print workflows still ask for. It cannot hold transparency, so flatten effects before exporting, or send PDF instead.
- AI is Illustrator's own format. Send it only if the shop asked for it by name and you are not worried about them editing the file.
If in doubt, send a PDF with the text outlined and the logo as a traced vector. That covers nearly every request a print shop will make.
Frequently asked questions
Is a PDF a vector file?
A PDF is a container that can hold both vector and raster content. A PDF exported from a design program is usually vector. A PDF made by scanning, or by exporting with a "rasterise" option, is not. Use the zoom test to tell them apart.
What does "vectorized PDF" mean?
It means a PDF where the important content, usually the text and the logo, is made of curves rather than pixels, and where no fonts are required to display it. In practice the shop wants text converted to outlines and any logo supplied as a vector shape.
Does converting text to outlines reduce quality?
No. The curves are mathematically identical to the glyphs the font would have drawn. The only things you lose are editability and text search, which is why you keep the original.
Can Illustrator open a vector PDF?
Yes. Illustrator, Affinity Designer, Inkscape and CorelDRAW all open PDFs and keep the vector content editable. Outlined text arrives as compound paths.
Can I convert a photo to vector?
You can trace it, but the result is a stylised illustration with flat colour areas, not a print quality photo. If a shop asks for a photo in vector, they need a higher resolution image instead.
How do I know the shop got what they asked for?
Open the file you are about to send, do the selection test on the headline (nothing should highlight if they asked for outlines), zoom to 800 percent on the logo, and run the Preflight Check. If all three pass, the file is ready.
The short version
Text to curves: Convert PDF Text to Outlines. Logo to SVG: Image to Vector. Vector file to PDF: Vector to PDF. Not sure which: Preflight Check first. All of them run free in the browser, files are processed on Nordic servers and deleted automatically, with a deletion certificate if you need one.
