The short version: Sending an AI design file means packaging it first (fonts, linked images, everything), choosing a transfer method that can handle a file that might be 200MB or more, and knowing when your recipient needs the editable file versus a flattened PDF or SVG. Get those three things right and you’ll stop getting the “it won’t open” email that ruins everyone’s Monday.
What people mean when they say “AI file”
An AI file is a native Adobe Illustrator file. It’s the working, editable version of a logo, a brochure layout, an icon set, whatever your designer built. It’s not a picture, it’s a construction document, full of vector paths, layers, and links to fonts and images that live outside the file itself.
That last bit is the whole problem. An AI file rarely travels alone. It drags fonts and linked images behind it like a bride’s train, and if you forget to send those along, the file opens for your recipient with big red X boxes where the images should be and a substitute font that ruins your carefully kerned logo. I’ve had a client’s brochure come back from their print shop with the headline in Times New Roman because the actual typeface, a paid font called Gotham, never made the trip.
Package it before you send anything
This is the step nine out of ten people skip, and it’s the one that causes almost every “the file’s broken” complaint I’ve dealt with over twenty-odd years of client work.
- In Illustrator, go to File, then Package. This gathers the AI file, every linked image, and every font used, into one tidy folder.
- Illustrator will ask where to save the package. Pick your desktop or a clearly named folder, not a random downloads folder you’ll never find again.
- Compress that whole folder into a ZIP before you send it. A ZIP survives email systems and cloud uploads far better than a loose folder with forty subfiles.
- If you’re on Illustrator 2020 or older, there’s no Package command, so you’ll need to manually collect the fonts and use File, then Save As, then check “Include Linked Files” in the dialogue that comes up.
Skipping packaging is the single biggest reason freelance designers get “urgent” calls on a Friday afternoon. The client hasn’t done anything wrong technically, they just didn’t know the file needed a chaperone.
Now decide how you’re sending it
The method matters more than most tutorials admit, mainly because of file size. A packaged AI file with a handful of high-resolution embedded photos can easily hit 150MB to 500MB. Compare that to Gmail’s flat 25MB attachment cap, and you’ll see the problem immediately.
- Email attachment: fine only for small, simple AI files under about 20MB. Anything with photography embedded, forget it.
- WeTransfer: the free tier handles up to 2GB per transfer and expires the download link after seven days, which is plenty for a one-off handoff to a printer or client.
- Dropbox or Google Drive: better for ongoing collaboration since you can drop updated versions into the same shared folder rather than re-sending links every time. Google Drive’s free tier gives you 15GB shared across Gmail and Photos too, so it fills up faster than you’d think if you’re a heavy image person.
- Adobe Creative Cloud sharing: if your recipient already has an Adobe account, sharing directly from within Illustrator via the Share button generates a link and lets them comment on the design without even opening the desktop app. underused.
I switched most of my own client handoffs to Dropbox shared folders about three years ago after WeTransfer links kept expiring before a client’s marketing manager got round to downloading them. A permanent folder with version history has saved more back-and-forth email chains than any single tool I’ve adopted in the past decade.
The uncomfortable bit nobody tells you
Here’s the part most guides on this topic will not say out loud: most of the time, the person asking for your AI file doesn’t need it, and handing it over is often a mistake, not a favour.
I learned this the expensive way. A client’s in-house marketing coordinator asked for “the raw AI file” of their new logo so their team could “make small tweaks in-house.” Three months later I got a panicked call because someone in their team had opened it in an old copy of Illustrator, stretched the mark to fit a banner, changed the brand blue to whatever their monitor happened to render, and sent it to a print vendor who ran two thousand banners before anyone noticed. Rebuilding trust with that client took longer than rebuilding the file.
If someone wants to view a design, use it in a document, or drop it into a slide deck, they need a PDF, PNG, or SVG export, not the editable master. If they want to print it, they need a print-ready PDF with fonts outlined, not the source file with live text. The AI file itself should really only leave your hands when the recipient is another designer who’s going to edit the vector paths and layers, not just look at them.
This matters for the same reason it matters when you’re building a lead magnet without design skills: giving someone the wrong format for their skill level doesn’t help them, it just creates a support ticket for you later.
Exporting instead of sharing the raw file
Nine times out of ten, what your client, colleague, or agency contact needs is one of these:
- PDF: File, then Export, then Export As, then choose PDF. Pick “Press Quality” for print, “Smallest File Size” for anything going by email or into a presentation. This is the safest universal format, almost everyone can open a PDF.
- PNG: for anything going on a website or social post. Export at 2x resolution for anywhere it might be viewed on a retina screen.
- SVG: for developers who need to drop your logo or icon straight into a website’s code without a bitmap. Small file, scales infinitely, no quality loss.
- EPS: increasingly outdated but some older print shops and merchandise vendors still ask for it specifically. Worth checking before you assume PDF will do.
Ask the recipient what they’re going to do with the file before you export anything. “I need it for the website” means PNG or SVG. “I need it for the printer” means a press-ready PDF. “I need to edit the text” means the packaged AI file, fonts and all. Skipping that one question is how you end up sending three different formats over three different emails because the first two guesses were wrong.
When you’re sending it to someone who doesn’t have Illustrator at all
This is more common than designers like to admit. A huge number of the people receiving AI files are marketing managers, print vendors, or small business owners who own zero Adobe software.
Adobe’s free web-based Illustrator viewer will open a shared Creative Cloud link in a browser tab, no subscription needed, so that’s your best option if the recipient just needs to look at the design or leave comments. For anything beyond viewing, export a PDF, since a PDF opens on literally every device without a single plugin.
I once sent a full packaged AI folder to a client who ran a small bakery chain, thinking her “design person” could open it. Her design person turned out to be her nephew with a free trial that had expired the week before. We lost two days waiting for him to sort software access before I just exported a print-ready PDF and sent that instead, which is what should have happened from the start. Always ask what software the other end has before you assume.
A quick word on version control
If you’re sending files back and forth more than once, name them. “Logo_final_v2_ACTUALFINAL_edited.ai” is a joke that every designer has lived, and it’s how mistakes happen, someone opens the wrong “final” and works from an outdated version.
Use a simple system: ProjectName_v1, ProjectName_v2, ProjectName_v3_APPROVED. Put the date in the filename if multiple people are touching the project in the same week. It sounds fussy but it’s saved me from sending an old logo to a printer more times than I’d like to admit.
The same logic applies to any link you’re handing out for people to find and use later, the same way a clear, intentional link beats a random one nobody can trace back to its source. A messy filename is just a broken link waiting to happen.
What to check before you hit send
- Open the packaged file yourself on a different machine if you can, before sending it, to catch missing fonts or broken links early.
- Check the file size against your chosen transfer method’s limit before you’re twenty minutes into an upload that’s about to fail.
- Confirm the recipient’s software situation with one direct question rather than assuming.
- Outline fonts (Type, then Create Outlines) if you’re sending a print-ready file to a vendor and you’re not certain they’ll have your fonts installed. This converts live text to shapes, so there’s nothing left to substitute.
- Rename the file something sane before it leaves your hands.
None of this is complicated. It’s five minutes of care that prevents the multi-day mess I’ve watched happen more times than I can count, on both sides of the client relationship.

Frequently asked questions
Can I open an AI file without Illustrator?
Yes, Adobe’s free web viewer opens shared Creative Cloud links in a browser, and programs like CorelDRAW or Affinity Designer can open many AI files directly, though complex ones with effects may not render perfectly. For guaranteed viewing, ask the sender for a PDF instead.
Why does my AI file show missing fonts or a red X when someone opens it?
Because AI files link to external fonts and images rather than embedding everything permanently. If you didn’t package the file (File, then Package) before sending it, those linked elements never travelled with it, so the recipient’s version of Illustrator has nothing to display.
What’s the biggest file size I can email as an AI file?
Gmail caps attachments at 25MB, and most other providers sit somewhere close to that. Anything larger needs WeTransfer (free up to 2GB), Dropbox, or Google Drive, all of which handle large packaged files without choking.
Should I ever send my logo’s raw AI file to a client or vendor?
Only if they’re specifically going to edit the vector artwork themselves. For viewing, printing, or using the logo on a website, export a PDF, PNG, or SVG instead. Handing over the editable master too freely is how brand colours and typefaces end up changed by someone with good intentions and the wrong tools.
