Step 1

Identify the likely rejection reason

Start with file type, extension, metadata, checksum, file size, supported-format, filename, and packet-manifest checks before changing the file or launching a server job.

File type checker Check a file's signature and reported type before opening it. Browser Magic bytes explorer Inspect file signatures to understand what a file really is. Browser File metadata viewer Inspect file metadata before sharing, uploading, or archiving. Browser File checksum Create hashes for files so you can verify downloads and handoffs. Browser

Step 2

Preflight PDF packets

Check size drivers, page count, page size, text-layer and scan signals, password protection, hidden content, attachments, metadata, and compression options before uploading a final PDF copy.

PDF file size inspector Review PDF size signals before upload or delivery. Browser PDF page count checker Count PDF pages without uploading the file. Browser PDF text layer checker Check whether a PDF already has selectable text. Browser Scanned PDF detector Find out whether a PDF is scanned, digital, or mixed. Browser PDF metadata viewer Inspect PDF metadata before publishing or sending a file. Browser Compress PDF Reduce PDF file size for email, upload portals, and sharing. Temporary upload Remove PDF metadata Clean basic PDF metadata before sharing a document. Browser

Step 3

Preflight image uploads

Check dimensions, aspect ratio, safe-area behavior, file-size targets, metadata privacy, format, and compression before uploading images to a strict destination.

Image dimensions checker Read image width, height, and basic size details. Browser Image aspect ratio inspector Check image proportions before resizing, cropping, or uploading. Browser Image format inspector Identify image format details before conversion or upload. Browser Resize image Resize JPG, PNG, or WebP images for uploads, email, and web pages. Browser Compress JPG Reduce JPG file size while keeping the image usable. Browser

Step 4

Preflight data and archives

Validate CSV structure, product-style headers, archive paths, duplicate names, nested archives, and upload chunk sizes before files are parsed, extracted, or imported by another system.

CSV validator Check CSV structure, headers, rows, and common import problems. Browser Product CSV validator Check product CSV rows before ecommerce import. Browser CSV header normalizer Clean CSV headers into consistent, import-friendly names. Browser CSV to XLSX Turn CSV data into an Excel workbook. Browser Archive path traversal checker Check ZIP paths for risky extraction targets. Browser List ZIP contents Preview files inside a ZIP before extracting anything. Browser
Workflow notes and help

Review PDFs, images, archives, CSV files, and Office documents before uploading them to file-size-limited portals or handoff systems.

Ready or needs review
  • Ready to retry: The file type, size, page count, dimensions, naming pattern, and packet manifest match the limits you entered or reviewed.
  • Needs PDF review: The PDF is encrypted, scanned, oversized, has unusual page sizes, hidden-content signals, attachments, or metadata that should be inspected before upload.
  • Needs image review: The image is the wrong format, too large, incorrectly sized, outside the needed aspect ratio, or still contains metadata/privacy signals.
  • Needs packet review: The ZIP, filename set, CSV headers, duplicate names, chunk size, or manifest details need attention before a handoff.
