Before you share.
What the app does, what it needs and where its limits are.
Can I resize a photo to 100 KB?
Yes. In Compress Photo, choose 100 KB and process the image. The target is an upper limit, not an exact file size. Output dimensions may be reduced to reach the target; inspect the result before submitting it.
Can I keep exact pixel dimensions as well as a file-size limit?
You can set pixel dimensions and compression options. Some combinations cannot be met without sacrificing the requested dimensions or image quality. The app reports the actual result rather than claiming every target is achievable.
How do I remove a signature or stamp background?
Open Signature & stamp, take a photo or select an image, crop around the ink, then adjust background removal. Export with Create transparent PNG. The checkerboard preview represents transparent areas.
Does it support blue stamps and colored signatures?
Yes. Keep original colors retains the detected ink colors. You can also select black, red, blue or a custom color. Red stamp is a filter for red ink; use All ink for blue or mixed-color marks.
What does Smart enhance do?
It automatically selects settings for paper-shadow removal, ink depth, edge clarity and small-gap repair. Processing uses local adaptive algorithms, not a bundled neural model. Large missing strokes or letters cannot be reconstructed reliably.
Do I need to watch an ad every time I adjust the signature?
Manual controls do not require a rewarded ad. Completing one offered ad unlocks Smart enhance retries for the current image in the current editing session. You can undo the enhancement. Replacing the image or starting a new session requires a new reward.
What if I close the ad or enhancement fails?
Closing an ad before completion does not unlock Smart enhance. If enhancement fails after you have completed the reward, you can retry in the same editing session without another ad. Manual processing remains available.
Are photos uploaded for processing?
Image editing runs on your device. These features do not upload your photos, signatures or stamps to an app-operated server. Ads and optional AppsFlyer measurement use network services. A cloud photo provider or a sharing app may handle data under its own policies.
Can I use the tools offline?
Local image processing can work offline once the source image is available on the device. Downloading a cloud photo and loading rewarded ads require connectivity and service availability.
Is the app free?
The app is ad-supported and currently has no in-app purchase or subscription. Manual tools are available without a rewarded ad. Smart enhance and larger batch processing use optional rewarded ads.
How many photos can I process in one batch?
A free batch processes up to 5 images. Completing an available rewarded ad expands that batch to up to 30 images. This does not permanently unlock larger batches.
Does a watermark make a photo impossible to copy?
No. A watermark adds a visible text or image mark. It does not prevent all copying, prove ownership or provide a cryptographic signature. Use only signatures, stamps and artwork you are authorized to use.
Which Android versions and languages are supported?
The app supports Android 7.0 and later, with light, dark and system themes. Interface languages include English, Simplified Chinese, Traditional Chinese, Hindi, Portuguese, Spanish and Indonesian.
How do I delete recent results?
Open Recent and delete an entry or clear the list. This removes the history record; exported gallery copies remain until you delete them in their gallery or file app. See Data & deletion for private-file cleanup details.
