Convert PNG to AI (Adobe Illustrator) Online

A PNG is a grid of coloured pixels. A .ai file contains geometry: coordinates, curves, and fill rules that describe shapes mathematically. Nothing in the PNG is geometry, so the conversion is not a re-save, it is a trace. Software has to look at where colour changes and decide where an edge belongs.

That distinction explains everything else on this page. Scale a PNG up and you get bigger pixels; scale a traced vector up and the maths is recomputed, so the edge stays sharp at any size. It also explains why the source matters: a 200px logo taken off a website carries far less edge information than the original file, and no tracer invents detail that was never captured.

The output here is written as real PDF path operators, which is what an Illustrator file is made of. Cubic curves stay cubic curves. That matters more than it sounds: a converter that flattens curves into hundreds of short straight segments produces a file that technically opens but is miserable to edit, because dragging a smooth arc means dragging two hundred anchor points.

Adobe has written Illustrator's native format as a PDF container since Illustrator 9, released in 2000. An .ai file has a PDF header, a PDF cross-reference table, and PDF content streams. This is documented behaviour, not a workaround: it is why "Create PDF Compatible File" has sat in Illustrator's save dialog for two decades, and why a properly formed PDF opens in Illustrator with selectable paths.

The older Illustrator 8 format is a different thing entirely: PostScript carrying Illustrator's own operator set. Some converters still emit it, and it is worth knowing why that can go wrong. A genuine AI 8 file ships a prolog declaring the operators it uses. Emit those operators without the prolog and you get a file nothing on earth can parse except Illustrator itself, if it feels generous.

Writing the PDF flavour instead means the output is verifiable: it can be opened, rendered and checked before it ever reaches you, rather than shipped on the assumption that it probably works.

This is worth stating plainly before you convert anything. Lettering does not come back as live type. If your PNG shows a company name, the trace produces outlined shapes in the form of those letters. You can recolour them, resize them, distort them, pull them apart. You cannot click into them and retype, and you cannot change the font.

The reason is simple: the PNG never contained the text. It contained a picture of text. There is no font name, no character codes, no baseline, nothing to recover. Any tool claiming otherwise is guessing at the typeface and will guess wrong on anything but the most common faces.

For most jobs this is fine, because the wording is already right and only the format was wrong. When you genuinely need live type, the honest answer is to set the text again in Illustrator over the traced logo mark, which takes a couple of minutes if you know the font, and to ask the client for the original file if you do not.

Four checks catch nearly every bad conversion, and they take longer to read than to do:

1. Open the counters. Zoom into an O, an A, an e, an 8. The holes must be holes. If they are filled solid, the fill rule was lost and the file is unusable for cutting or screen work.
2. Select a shape and drag it. One click should grab one shape, not a hundred fragments. If a single letter is made of dozens of overlapping slivers, the trace over-segmented and the file will fight you.
3. Look at a curve at 800%. A smooth arc should stay smooth. Visible facets mean the curves were flattened into straight segments.
4. Recolour something. Pick a shape, change its fill. If a logo colour is spread across twelve near-identical shapes, recolouring it becomes a chore, and merging near-duplicate colours before export saves that pain.

If you are sending the file onward to a machine rather than to a designer, take the DXF or G-code export from the same conversion instead of converting twice.

Walk through the artwork requirements published by screen printers, embroiderers and sign makers and the same two extensions appear: .ai or .eps. The reason is practical rather than dogmatic. A shop needs to separate colours for screens, offset a cut path for a plotter, or hand clean outlines to a digitizer before a single stitch is planned. All of that is editing, and editing needs geometry.

What arrives instead is usually a JPG off a phone, a screenshot, or a logo pulled from the customer's own website at 600 pixels. Somebody in the shop then either redraws it by hand, which is twenty-five to forty minutes, or sends it to an art service at twenty-five to sixty dollars a file. That gap between what is asked for and what turns up is the entire reason this page exists.

If that describes a normal week at your shop rather than an occasional annoyance, the Production plan is a flat monthly price for the whole shop rather than a charge per file. If it happens twice a year, use the converter above and ignore the plan.
