Room for detail
Two hundred kilobytes is a middle-ground limit. It shows up on website contact and support forms, on applications that accept a photo of a document, on community and club registrations, and on profile sections that display your picture at a larger size. It's small enough that a raw phone photo won't pass, but big enough to keep real detail.
That makes it a good fit for images where something has to be read: a photo of a receipt, a certificate, a handwritten note or a product label. Faces look natural and small text usually stays legible.
Photos of documents
When you photograph a document, most of the file goes to things nobody needs: the table under the paper, shadows and the camera's full resolution. Crop to the edges of the page with “Crop image” first. Then compress here. A cropped document photo at 200 KB is usually perfectly readable on screen.
If the form actually expects a PDF, use “JPG to PDF” on the compressed image, or photograph the document with “Scan to PDF”, which straightens the page and applies a black-and-white document filter.
How the 200 KB target works
ConvertirDocs looks for the best quality that still fits under 200 KB. If the photo is too big even at low quality, it reduces the dimensions step by step until it fits. If the target still can't be met, you get the smallest version achieved and a message saying so. You always see the size before and after and the percentage saved.
If compressing wouldn't make your image any smaller, for example when it's already under the limit, you get the original back unchanged.
Choosing a format
JPG is the safest output for photos and accepted almost everywhere. WEBP is often lighter at the same quality, good for your own website, but check that the form you're using accepts it. For screenshots and graphics with flat colors, PNG works well: ConvertirDocs reduces it to a palette of up to 256 colors, which can make it much lighter without visible change.
