Common questions.
Scanning & import
The scanner isn't detecting my document's edges. What can I do?
Edge detection works best with strong contrast — place the document on a dark, plain surface with even lighting and avoid shadows. If auto-detect still struggles, tap anywhere in the preview to switch to manual crop and drag the corners yourself.
How do I scan multiple pages into one PDF?
Keep capturing — after each shot, the page is added to the current session. Tap the page counter to review, reorder, or retake pages, then tap Save to produce a single multi-page PDF.
Can I import existing photos or files?
Yes. Use Import on the home screen to pull from your photo library or the Files app. Images become scanned-style documents; PDFs open directly in your library.
PDF tools
Where do my edited files go?
Every tool saves its result as a new document in your library — the original is never overwritten unless you explicitly choose to replace it. Use the share sheet to export anywhere else.
Why did my compressed PDF not get much smaller?
Compression mostly shrinks embedded images. Text-only or already-optimized PDFs have little left to squeeze. For scans, try a stronger compression level or re-save pages as grayscale.
OCR recognized the wrong language. How do I fix it?
Open the OCR tool and set the document language before running recognition. Multi-language documents can select more than one language. Clear, well-lit scans dramatically improve accuracy.
iCloud
How do I sync my library between iPhone and Mac?
Sign both devices into the same Apple ID with iCloud Drive on, then open Settings → iCloud → Sync Library in Dococo. Documents, folders, and Recently Deleted items appear on the other device after iCloud finishes uploading. Sync is off until you turn it on.
What if a document shows “Downloading from iCloud”?
iCloud keeps full-size files in the cloud until you open them. Stay on Wi-Fi, keep the app open, and wait for the download to finish. Very large PDFs can take a minute on a slow connection.
Premium & billing
How do I restore my Premium purchase on a new device?
Make sure you're signed into the same Apple ID used for the purchase, then open Settings → Premium → Restore Purchases in the app. Your entitlement syncs automatically.
How do I cancel my subscription?
Subscriptions are managed by Apple: go to Settings → [your name] → Subscriptions → Dococo on your device and tap Cancel. Premium stays active until the end of the current billing period.
Can I get a refund?
Refunds are issued by Apple. Visit reportaproblem.apple.com, sign in, and select your Dococo purchase. Apple typically responds within 48 hours.
