Not sure where to start?
A photo must fit both pixels and KB
Read the upload form's required dimensions, format and file-size limit first. Resize the image to the correct dimensions, then reduce its KB size if needed. Small size targets can reduce dimensions again, so check the downloaded result against both limits.
Several documents need to become one PDF
Use Merge PDF for existing PDFs. For photos or scans, use JPG to PDF instead. Add files in the required order and review every output page. Converting a photo into a PDF does not recognize its text.
A PDF exceeds a file-size limit
Start with Compress PDF and choose clean re-save if searchable text matters. Strong image compression can make scans smaller, but can remove selectable text and form fields. Keep the original and inspect small print, signatures and codes after downloading.
Check the result before submitting
FileHoney prepares files; it cannot guarantee that a receiving website will accept them. Confirm the actual file size, dimensions, page order and readability. For passport or application photos, follow the receiving authority's current instructions rather than relying on a preset.
