If an image won’t upload or doesn’t appear after uploading, the cause is almost always one of four things: an unsupported file format, a file that’s too large, an image that’s too small, or a browser issue. Work through the checks below in order.

​
1. Check the file format

Standard image options accept JPG, PNG, GIF, WebP, and many other common image formats. Several question types are stricter — Image Sets, Click Tests, and 5-Second Tests accept JPG, PNG, and GIF, while SERP mockups accept JPG and PNG. If you’re uploading a PDF, convert it to PNG or JPG first. PDF uploads are a common source of failures — a PDF is a document format, not a native image, and multi-page files especially can fail or display incorrectly. Exporting to PNG or JPG takes seconds in most design tools and is the reliable path. See What types of content can I test with PickFu?

2. Check the file size and dimensions

  • Maximum file size: 20 MB per image. Larger files won’t upload — compress or resize the image first.
  • Minimum width: 800 pixels for standard surveys and Image Sets (1,000 px for Click Tests, with 1,200–1,600 px recommended). Images below the minimum may be rejected or look blurry to respondents.

3. Check your browser

If the file itself is fine but the upload stalls or the image doesn’t appear in the builder:
  1. Refresh the page and try the upload again.
  2. Disable ad blockers or privacy extensions temporarily — they can interfere with uploads and previews.
  3. Try a different browser (Chrome, Firefox, Safari) or a private/incognito window.
  4. Check your connection — large images on a slow connection can time out silently.
  5. Check PickFu’s status page — if uploads that worked yesterday are failing today across browsers, check status.pickfu.com for any active system issues before troubleshooting further.

​
4. Preview before you launch

Always use the Preview function before publishing. If an image didn’t upload correctly, respondents can’t evaluate your options properly, and PickFu’s quality systems may stop the survey early. Catching a broken image in preview costs nothing; catching it after launch means stopping the survey and relaunching with the credit. See Why was my survey stopped early?

FAQs

​
My image uploaded but looks stretched or cropped

Keep aspect ratios consistent across all options in the same survey — mismatched ratios display inconsistently and can bias which option draws attention. When the survey builder shows the Resize images to match? prompt, click Resize all images to normalize aspect ratios with white padding. You can also resize your images to matching dimensions before uploading. See What are the image requirements for PickFu surveys?

​
PDFs worked for me before — why not now?

PDF handling is less reliable than native image formats, so a PDF that uploaded once may fail another time — especially multi-page files. Converting to PNG or JPG is the reliable path and takes seconds in most design tools.

​
The image shows in the builder but respondents reported it missing

Stop the survey from your results page (you’ll receive a prorated credit for unfulfilled responses), then duplicate the survey, re-upload the image, confirm it in Preview, and relaunch.

​
Where do I resize or compress an image?

Any image editor works. Free browser tools like Pixlr can resize and compress without installing anything.
