Export as PDF or high-resolution image to keep details crisp
InDesign's default export settings often compress images and reduce quality. To keep images sharp, you need to change two things: the export format and the resolution setting. The clearest results come from exporting as PDF with high quality settings, or as a TIFF or PNG file at 300 dots per inch (DPI) or higher. Which one you choose depends on what you plan to do with the file next — print it, post it online, or hand it to someone else to edit.
The most common mistake is exporting at screen resolution (72 DPI), which makes photographs and detailed graphics look blurry. Print shops and professional printers need 300 DPI minimum. If you are sharing work online or sending a proof to a client, 150 DPI is usually enough and keeps file size smaller.
Key Takeaways
- Export as PDF with "High Quality Print" preset, or as TIFF or PNG at 300 DPI, to preserve image sharpness for print.
- Screen resolution (72 DPI) makes images look blurry; use 150 DPI minimum for digital sharing and 300 DPI for printing.
- Uncheck "Compress" and "Downsample" options in the export dialog to prevent InDesign from reducing image quality.
- Test your export settings on a small file first, then check the result at actual size before exporting your full project.
Export as PDF for the sharpest, most reliable result
PDF export is the safest choice because it preserves all image quality and fonts exactly as they appear in InDesign. Go to File > Export, choose Adobe PDF as the format, and click Save. In the dialog that opens, select "High Quality Print" from the Adobe PDF Preset dropdown at the top left. This preset automatically sets compression to "None" and resolution to 300 DPI.
If you do not see "High Quality Print" in the list, click the dropdown and look for "Press Quality" — both work equally well. Avoid "Smallest File Size" or "Standard" presets; these compress images and make them look soft. After selecting the preset, click Export and your PDF will be ready. The file will be larger than a compressed version, but the images will be sharp.
PDF works well for sending to print shops, sharing with clients, or archiving your work. It is also the format most designers expect to receive. The only drawback is that PDF is harder to edit later — if you need to change the design, you have to go back to the InDesign file.
Export as TIFF or PNG if you need an editable image file
If you need a single image file instead of a PDF — for example, to post on a website or import into another program — export as TIFF or PNG. Both formats preserve quality without compression. Go to File > Export, choose TIFF or PNG from the format dropdown, and click Save.
In the export options dialog, set Resolution to 300 DPI if the image is for print, or 150 DPI if it is for a website or screen. Leave Compression unchecked (for TIFF) or set it to "None" (for PNG). TIFF files are larger but work with almost any professional software. PNG files are smaller and better for web use, but some older print shops may not accept them. Ask your printer which format they prefer before you export.
One important note: exporting from InDesign as TIFF or PNG flattens all layers and converts the entire page to a single image. If your InDesign file has multiple pages, you will get one image per page. This is different from PDF, which keeps pages separate.
Turn off compression and downsampling in the export dialog
InDesign has hidden settings that reduce image quality by default. After you choose your format and click Export, look for these options in the dialog that appears:
- Compress — uncheck this box entirely. Checked compression reduces file size by throwing away image data.
- Downsample — uncheck this or set it to "None". Downsampling reduces the number of pixels in your images, making them blurry.
- Quality — if you see a quality slider, move it all the way to "Maximum" or "High".
These settings are straightforward to miss because they are often in a collapsed section labeled "Compression" or "Image Handling". Click the arrow next to that label to expand it and see all options. After unchecking compression and downsampling, click Export. Your images will be much sharper than if you had left these boxes checked.
Check your resolution before exporting a large project
Before you export your entire InDesign document, test your settings on a small section. Create a new export with just one page or one image, then open the result at actual size (100 percent zoom) and look closely at text and photo details. If the image looks soft or pixelated, go back and check your DPI setting — it may be too low.
Common DPI settings and what they are for:
| DPI | Best For | File Size |
|---|---|---|
| 72 | Screen preview only (not recommended) | Smallest |
| 150 | Website, email, digital sharing | Medium |
| 300 | Print, professional output | Largest |
If you are exporting for print and your file is very large, you can use 240 DPI as a compromise — it is sharp enough for most printing and keeps file size a bit smaller than 300 DPI. Professional print shops usually ask for 300 DPI, so check with them first.
Why InDesign images look blurry without these changes
InDesign's default settings assume you are exporting for quick preview or web use, not for print or professional output. By default, it compresses images, reduces resolution, and sometimes downsamples (shrinks) the actual pixel data. These changes make files smaller and faster to send, but they make images look soft and lose fine detail.
The images in your InDesign file are stored at their original quality — the problem happens only during export. This means you can export the same file multiple times with different settings. Export once at 72 DPI for a quick email preview, then export again at 300 DPI for print, and both will work without affecting your original InDesign document.
Frequently Asked Questions
What is the difference between PDF and TIFF export?
PDF keeps your entire page layout, fonts, and images together in one file that looks the same on any computer. TIFF converts the page to a single flat image, like a photograph. Use PDF for sharing designs and printing; use TIFF if you need a standalone image file for another program.
Why does my exported image look pixelated even at 300 DPI?
Check that you unchecked the Downsample option — if it is still on, InDesign is reducing the pixel count even though you set 300 DPI. Also make sure the images in your InDesign file are high resolution to begin with. If you placed a 72 DPI image in InDesign, exporting at 300 DPI will not make it sharper.
Can I export just one image from InDesign instead of the whole page?
Yes. Select the image with the Selection tool, then go to File > Export. InDesign will export only the selected object. This is faster if you only need one photo or graphic from a larger document.
What file size should my exported PDF be?
A PDF with high-quality images is usually 5 to 50 MB depending on the number of images and page size. If your PDF is under 1 MB, compression is probably on and images may not be sharp. If it is over 100 MB, check that you are not exporting at unnecessarily high resolution or including unnecessary elements.
Do I need to change anything in InDesign before exporting, or just the export settings?
Just the export settings. Your InDesign file itself does not need to change. Make sure any images you placed in InDesign are high resolution (300 DPI or higher) to begin with, but you do not need to edit them — InDesign will export them at whatever resolution you choose in the export dialog.
