PNG with transparent background recommended
💡 Why PNG? So your logo doesn't have a white box around it on the cover page.
No logo yet
No logo yet? You can use Canva, Google Slides, or even a Word document to create a simple logo. Export it as PNG. A simple text logo works fine — "Smith Law Firm" in a nice font is professional enough.

Your cover page is ready!
It will automatically be attached as the first page of every fax you send. You can also turn it off per-fax in the Send Fax screen.
Why document quality matters for faxes
Fax technology transmits at 200×200 DPI in grayscale. If your document isn't optimized before sending, the recipient gets blurry, unreadable pages. EZFax Flow Pro automatically normalizes every document before transmission — this is what makes us premium.

delivery clarity rate
Files We Reject — and Why
These file types cause failed or unreadable fax transmissions. EZFax Flow Pro blocks them before they waste your pages or the recipient's time.
Phone Screenshots / JPGs
Random screenshots are RGB color, arbitrary resolution, and often contain UI chrome (time, battery bars). Result: garbled grayscale noise at the recipient end.
BLOCKED — convert to PDF first
Giant Phone Camera Images
A 12MP phone photo is 4000×3000px in portrait. Fax only uses 1728px wide. Sending unscaled images causes cropping, rotation issues, and massive file sizes that time out.
BLOCKED — we resize & optimize
Low-Resolution Scans
Scans below 150 DPI produce text that is unreadable after grayscale conversion. Medical records, legal documents, and contracts faxed at low DPI can be inadmissible in court.
REJECTED — minimum 150 DPI
Automatic Processing Pipeline
Every document goes through these steps automatically before transmission. Each step is configurable.
1. Intake
Accept PDF, DOC, DOCX, JPG, PNG, TIFF
2. Convert to PDF
All formats rendered to single standardized PDF
3. Grayscale
Strip all color — pure fax-compatible black & white
4. DPI 200×200
Normalize to exact fax standard — no more, no less
5. Enhance
Auto contrast, auto sharpen, noise removal
6. Send via Telnyx
T.38 protocol — guaranteed delivery
Conversion Settings
Applied to every document before sending
Output Resolution
Fax standard is 200×200 DPI. Do not change unless you know why.
Color Mode
Fax only transmits grayscale. Color wastes bandwidth.
Force grayscale ON — always enabled for fax
Paper Size Normalization
Force all pages to Letter (8.5×11") or A4 before sending
Minimum Accepted DPI
Files below this are rejected with an error message
Image Enhancement
Applied after conversion — makes text crisp and readable
Auto Contrast
Stretches the histogram so dark text becomes black and white backgrounds become white. Essential for scanned documents and phone photos.
SubtleMedium ✓Aggressive
Auto Sharpen
Applies unsharp mask to recover text edges lost during resize/conversion. Especially important for signatures and small print.
LightMedium ✓Strong
Page Cleanup
Removes scan artifacts: coffee stains, punch holes, shadow edges, specks, and gray backgrounds. Makes pages look professionally prepared.
Auto Deskew
Detects and corrects pages scanned at an angle. A document scanned tilted 2° will look crooked on the fax — this fixes it automatically.
CCITT Group 4 Compression
The official fax compression standard. Reduces file size by up to 20× without quality loss. Transmits faster and uses less of your page quota.
