How to Change DPI in Adobe Illustrator

Where to find the DPI setting in Illustrator

Adobe Illustrator does not have a single "DPI" button you can click. Instead, you control resolution through the document setup and export settings. The DPI (dots per inch) that matters depends on what you are making — a screen graphic uses different settings than a print file.

For a new document, go to File > New and choose a preset that matches your output. If you are designing for print, select "Print" from the document type menu. If you are designing for screen, select "Web". These presets set the color mode and artboard size correctly from the start, which affects how Illustrator handles resolution later.

For an existing document, you can change the color mode and document settings by going to File > Document Setup. This window shows your artboard dimensions and color mode (RGB for screen, CMYK for print). Changing the color mode here does not change DPI directly, but it prepares your file for the right output method.

Key Takeaways

Illustrator is vector-based, so it does not store DPI the way a photograph does — DPI only matters when you export or print.
When you export to a raster format like PNG or JPG, the export dialog has a "Resolution" field where you set DPI (usually 72 for screen, 300 for print).
For print output, use File > Print and check the printer settings, where DPI is often called "Quality" or "Print Quality".
Creating a new document with the correct preset (Print or Web) from the start saves you from having to change settings later.
Vector artwork stays sharp at any size, so changing DPI only affects the final exported image, not the original file.

Setting DPI when you export to PNG, JPG, or PDF

This is where most people change DPI in Illustrator. When you export your artwork to a format that needs a fixed resolution, the export dialog gives you control. Go to File > Export As (or Export in older versions).

Choose your file format from the dropdown at the bottom. If you choose PNG or JPG, a dialog box opens with export options. Look for the "Resolution" field — this is your DPI setting. For screen use (web, email, social media), enter 72 DPI. For print, enter 300 DPI. Some print jobs ask for 150 DPI as a middle ground, but check with your printer first.

If you are exporting to PDF, the resolution field works the same way. PDF is often used for both screen and print, so 300 DPI is safer if you are unsure. The higher the DPI, the larger the file size, so do not use 300 DPI for a web image — it wastes space and slows down loading.

Changing DPI for print output

If you are printing directly from Illustrator instead of exporting first, DPI is controlled by your printer, not Illustrator itself. Go to File > Print to open the print dialog.

In the print dialog, look for a "Setup" or "Printer Properties" button. Click it to see your printer's settings. The DPI option is usually labeled "Quality", "Print Quality", or "Resolution" — the exact name depends on your printer model. Select the highest quality option available, which is usually 1200 DPI or higher for modern printers. Your printer will handle the conversion automatically.

Before you print, make sure your document is set to CMYK color mode if you are using a color printer. Go to File > Document Setup and check the color mode. If it says RGB, your colors may look different in print than on screen. Change it to CMYK, and Illustrator will convert the colors for you.

Understanding DPI versus PPI in Illustrator

You may see both "DPI" and "PPI" mentioned in Illustrator's settings. DPI stands for dots per inch and is used for printers. PPI stands for pixels per inch and is used for screens. In Illustrator's export dialog, the field is often labeled "Resolution" and measured in PPI, but the number works the same way — 72 PPI for screen, 300 PPI for print.

Illustrator treats them interchangeably because the math is the same: more dots or pixels per inch means a sharper, higher-resolution image. The difference only matters when you are talking to a printer (they use DPI) or a web developer (they use PPI). For your purposes in Illustrator, use 72 for screen and 300 for print.

Common mistakes when changing DPI

The biggest mistake is changing DPI in the document setup and expecting it to affect your exported file. Document setup controls artboard size and color mode, not resolution. DPI only gets set when you export or print. If you change the document setup but forget to set DPI in the export dialog, your file will export at the default 72 DPI, which is too low for print.

Another mistake is using 300 DPI for web images. A 300 DPI PNG file is four times larger than a 72 DPI version of the same image, and browsers display both at the same size on screen. The extra file size just slows down your website. Use 72 DPI for anything going on the web.

A third mistake is exporting to JPG for print work. JPG uses compression that can create visible artifacts (blurry or blocky areas) in detailed artwork. For print, export to PDF or TIFF instead. JPG is fine for web and email.

Checking your DPI before you send a file to print

If you are sending your Illustrator file to a professional printer, they usually ask for a PDF. Before you create that PDF, go to File > Export As, choose PDF from the format dropdown, and set the resolution to 300 DPI. Click "Export" and name your file.

A dialog box appears with PDF options. Look for "Compression" settings and make sure "Preserve Illustrator Editing Capabilities" is unchecked — this keeps the file size down. Then click "Export" to save the PDF.

Open the PDF in Adobe Reader or Preview to check that it looks correct. Zoom in to 100% and look for any blurry text or pixelated artwork. If it looks sharp, you are ready to send it to the printer. If it looks blurry, go back to Illustrator, export again, and try 400 DPI instead.

Frequently Asked Questions

Can I change the DPI of an Illustrator file after I create it?

Yes, but only when you export. The original Illustrator file (.ai) does not store DPI because it is vector-based. Every time you export, you choose the DPI for that specific export. You can export the same file at 72 DPI for web and 300 DPI for print without changing the original.

What DPI should I use for a file I am sending to a professional printer?

Ask the printer directly — different printers have different requirements. Most ask for 300 DPI, but some accept 150 DPI or require 400 DPI. It is faster to ask than to guess and have to re-export. Always get the answer in writing so you have it for next time.

Why does my exported image look blurry even though I set it to 300 DPI?

Check that you exported to the right format. JPG compression can make images look blurry, especially if your artwork has thin lines or small text. Try exporting to PNG (which does not compress) or PDF instead. Also make sure your artboard is large enough — if you are exporting a tiny artboard at 300 DPI, the image will be small and may look pixelated when enlarged.

Do I need to change DPI if I am only sharing the file on screen?

No. For email, social media, or websites, use 72 DPI. Higher DPI makes the file larger without any visible improvement on screen. Save your file size and stick with 72 DPI for anything that stays digital.
