Where to find the resolution setting in Illustrator
Resolution in Illustrator lives in the document setup, not in a standalone menu. Open the file you want to change, then go to File > Document Setup. A dialog box opens showing your current settings. The resolution field appears under the heading Raster Effects, and it shows a number followed by "ppi" (pixels per inch).
If you have not yet created a document, you can also set resolution when you start. Go to File > New, and the New Document dialog includes a Raster Effects section with the same resolution field. Setting it here before you begin work saves you the step of changing it later.
The resolution you see here controls how Illustrator renders effects like drop shadows, glows, and blur when you export or print. It does not change the vector art itself — vectors stay sharp at any size. Resolution only matters for the raster (pixel-based) parts of your file.
Key Takeaways
- Resolution in Illustrator is found under File > Document Setup in the Raster Effects section, measured in ppi (pixels per inch).
- Changing resolution affects only raster effects like shadows and blur, not the vector shapes that make up your artwork.
- Screen work typically uses 72 ppi, while print work usually needs 300 ppi or higher depending on your printer's requirements.
- You can set resolution when creating a new document or change it anytime before exporting or printing.
- The resolution setting in Document Setup is separate from the export resolution you choose when saving as PNG, JPG, or PDF.
Why resolution matters for different outputs
The resolution you set in Document Setup determines how crisp or soft your raster effects appear in the final output. A lower resolution (72 ppi) is fine for work you will only view on screen — websites, presentations, social media. A higher resolution (300 ppi) is standard for print because printers need more pixel information to render fine detail without visible pixelation.
If you are designing a logo that will appear both on a website and on a business card, you might start at 300 ppi so the print version looks sharp. The screen version will still display correctly; Illustrator straightforward uses the higher resolution data. Conversely, if you set resolution too low for print (say, 72 ppi) and then try to print, any drop shadows or blur effects will look jagged or soft.
Some designers work at 300 ppi from the start, even for screen-only work, because it gives them flexibility if the project scope changes later. The trade-off is that effects render more slowly on older computers, but the difference is usually small.
Steps to change resolution in an existing document
Open the document you want to modify. Go to File > Document Setup. In the dialog that appears, look for the Raster Effects section. You will see a field labeled Resolution with a number and "ppi" next to it.
Click in the resolution field and type the new value. Common choices are 72 ppi for screen, 150 ppi for draft printing, and 300 ppi for final print. After you enter the number, click OK. Illustrator applies the new resolution to any raster effects in your document.
If you have already applied effects like drop shadows or glows, they will re-render at the new resolution. This happens automatically and usually takes a few seconds. You do not need to reapply the effects yourself.
Resolution versus export settings
Do not confuse the resolution in Document Setup with the resolution you choose when exporting. When you save your file as a PNG, JPG, or TIFF, Illustrator asks you to set resolution again in the export dialog. These are two separate controls.
The Document Setup resolution controls how effects render while you work and how they appear in the final file. The export resolution controls how Illustrator converts your entire document to pixels when you save it as an image format. If you export as PDF, the export dialog does not ask for resolution — PDF preserves your vectors and raster effects as they are.
For example: you might set Document Setup to 300 ppi so your drop shadows look sharp, then export as PNG at 150 ppi to create a smaller file for the web. The PNG will use the 150 ppi setting you chose at export time, not the 300 ppi from Document Setup.
Common resolution settings for different uses
| Use | Typical Resolution | Why |
|---|---|---|
| Website, social media, screen display | 72 ppi | Screens display at 72 ppi; higher resolution adds no visible benefit and slows rendering. |
| Draft or internal printing | 150 ppi | Acceptable for proofs and internal use; effects look reasonably sharp without the file overhead of 300 ppi. |
| Final print (business cards, brochures, posters) | 300 ppi | Standard for professional printing; ensures raster effects are crisp and detail is preserved. |
| High-end print (fine art, photography) | 300–600 ppi | Some specialty printers request higher resolution for maximum detail, but 300 ppi is sufficient for most work. |
What happens if you change resolution after adding effects
If you have already added drop shadows, glows, feathering, or other raster effects to your artwork, changing the resolution will re-render those effects at the new ppi. You do not lose the effects or have to reapply them. Illustrator straightforward recalculates how they look based on the new resolution.
Increasing resolution (for example, from 72 to 300 ppi) makes effects sharper and more detailed. Decreasing resolution (from 300 to 72 ppi) makes them softer and less precise. If you have a complex document with many effects, the re-render may take a few seconds, but it happens in the background.
If you want to see the change when ready, you can also go to View > Raster Effects Settings and toggle the preview on and off. This is useful if you want to compare how your effects look at different resolutions before committing to a change.
Frequently Asked Questions
Does changing resolution make my vector artwork bigger or smaller?
No. Resolution only affects raster effects like shadows and blur. Your vector shapes — lines, text, and fills — stay exactly the same size and remain infinitely scalable. You can enlarge or shrink the entire document using the artboard size, but that is separate from resolution.
What resolution should I use if I do not know where the file will end up?
Start at 300 ppi. It works for both screen and print, and you can always reduce it later if you need a smaller file. The only downside is slightly slower effect rendering on older computers, which is rarely noticeable.
Can I change resolution for just one artboard in a multi-artboard document?
No. Resolution is a document-wide setting in Illustrator. All artboards in the file use the same resolution. If you need different resolutions for different parts of your work, you will need to create separate documents.
Does resolution affect file size?
The Document Setup resolution does not directly change your Illustrator file size, because Illustrator stores vector data, not pixels. However, higher resolution makes raster effects more detailed, which can slightly increase file size. The bigger impact on file size comes when you export — exporting at 300 ppi creates a much larger PNG or JPG than exporting at 72 ppi.
What if my printer asks for a specific resolution?
Set Document Setup to match what your printer requests, usually 300 ppi. If your printer specifies something unusual (like 150 ppi or 600 ppi), use that number. Your printer's documentation or your print vendor can tell you what they need.
