An online form may reject a perfectly readable document because the image dimensions, file size or format do not match its requirements. A good workflow starts with the receiving portal’s instructions, then works backwards to the file you need. DocuKit brings photo and PDF tools into one Android app, but the portal’s own rules remain the final reference.
1. Write down the requirements first
Check whether the portal asks for JPG, PNG or PDF; note the minimum and maximum file size and any exact pixel dimensions. A passport photograph, a signature and a scanned certificate can have different requirements on the same form. Keep the original file untouched so you can try again without repeatedly compressing an already compressed image.
2. Crop before resizing
Remove unnecessary background while keeping the complete document or required portrait framing. Then use DocuKit’s supported resizing tools to choose the target dimensions or file size. Check the result at a readable zoom level: making the file smaller is not helpful if a name, stamp or signature becomes unclear. Avoid editing document information or altering an official record.
3. Build the PDF in the right order
If the portal accepts one PDF, arrange the pages in the requested sequence. DocuKit supports images-to-PDF, merging, splitting and selected-page extraction. Open the completed document and confirm page order, orientation and readability before sharing it. Compression results vary with the source file; encrypted or complex PDFs may not support every operation.
4. Export a clearly named final copy
Use a name you can recognise, such as application-certificate-final.pdf. Processed files are available through DocuKit’s My Files area and can be exported or shared. Before uploading, check the actual exported file rather than assuming it matches a previous preview. Keep a backup somewhere you control, especially before clearing app data or changing phones.
Final submission check
- The format, size and dimensions match the portal’s current instructions.
- Every page is readable and correctly oriented.
- The file contains only the information requested.
- You are uploading through the intended official portal.
