DOKUNTAG Solution Guide
A practical way to reduce a photo to a target file size such as 200 KB or 500 KB on iPhone, without uploading the image to a DOKUNTAG server.
Quick answer
If the requirement is a file-size limit, set the target in KB or MB instead of guessing a quality percentage. Image Tools DOKUNTAG can prepare a smaller output toward that target on the device, then you review the result before saving it as a new file.
How to
Image compression depends on the photo itself. Detailed textures, noise, transparency, dimensions, and output format all affect how small the file can become without excessive quality loss. A target is therefore a preparation goal, not a promise that every image can land on the exact same byte count.
Only when the destination also has a dimension requirement or the source image is much larger than you need. Reducing unnecessary pixel dimensions can make a smaller file easier to achieve. If the destination requires exact dimensions, solve the dimensions first and file size second.
Image Tools DOKUNTAG performs its photo-processing workflow on the device. The photo is not uploaded to DOKUNTAG servers for this processing, and an account is not required for core use.
