Frequently asked questions
Shrinkora FAQ
Which image formats can Shrinkora compress?+
Shrinkora supports JPEG, PNG, and static WebP input. It can also read HEIC or HEIF when the Android device provides a compatible decoder.
Which formats can Shrinkora create?+
Shrinkora can create JPEG, PNG, and WebP images. Auto output chooses a format based on the source image, transparency, and selected optimization goal.
Can I compress an image to 100 KB?+
Yes. Choose the 100 KB shortcut or enter 100 in Target Size and select KB. The result page shows the actual output size.
Is the target size guaranteed exactly?+
No. Shrinkora aims for the target or below, but image complexity, transparency, quality limits, and safe dimensions can make very small targets unreachable. The app shows the closest possible result when needed.
How many images can I compress at once?+
Up to 50 images per batch.
Can Shrinkora resize images?+
Yes. Resize from 1% to 100%, or enter a width and height from 32 to 16,384 pixels. Shrinkora does not enlarge smaller source images.
Does Shrinkora preserve PNG transparency?+
Yes. Select PNG or Keep PNG to preserve transparency. Smaller Files can use WebP when you want a smaller transparent output.
Why does an image sometimes show “already near optimal”?+
The source may already be below the target, or another encoding may not produce a smaller file. Shrinkora keeps the source result instead of creating a larger duplicate.
Does Shrinkora upload my images?+
No. Selected image content is processed on your device and is not uploaded to a Shrinkora server.
Does Shrinkora need access to every photo or file?+
No. Shrinkora uses Android's system photo and file pickers, so you choose the specific items it can read.
Where are saved images stored?+
On Android 10 and later, saved images appear in Pictures/Shrinkora. On Android 7–9, the system asks you to choose an output folder when saving.
Does Shrinkora overwrite or delete the original image?+
No. It creates a separate output file and leaves the selected source image untouched.
Can Shrinkora compress videos or PDF files?+
No. The current release focuses on still-image compression, resizing, and format conversion.
Where can I download Shrinkora?+
Shrinkora is available for Android on Google Play at https://play.google.com/store/apps/details?id=com.pasta.shrinkora.
