How to check PDF size before emailing it
The annoying part of emailing a PDF is usually not writing the message. It is getting all the way to the attachment step and finding out the file is too large for the mailbox, the client, or the recipient's workflow. That is why a calm pre-send check matters. If you know the PDF's size before you attach it, you can decide whether the file is ready, needs compression, or should be trimmed into a smaller, cleaner copy.
Decision map
What to remember before choosing a file.
Checking the PDF size first is the fastest way to avoid a last-minute attachment rejection.
PDFTry's size-check route creates a small local TXT report with the file size and page count instead of uploading the PDF somewhere first.
If the file is too large, the next honest options are usually compressing it, deleting unneeded pages, or splitting the document into smaller parts.
Local workflow
Use the no-upload route in four moves.
Chapter 1
Why this step matters before you even open email
Attachment limits are one of those small workflow traps that waste time because they appear at the end. You choose the file, write the note, and only then learn the handoff is too heavy. A size check flips that sequence around. Instead of guessing whether the PDF will send, you make the send-or-fix decision early while the document is still in your local workflow.
Chapter 2
Treat size checking as a routing decision, not just a measurement
The number itself is only half the point. Once you know the file size, you can choose the next action with less stress. A PDF that is already small enough can move straight to email. A PDF that is a little too large probably needs compression. A packet with obvious extras may be better served by deleting pages or extracting only the pages the recipient actually needs.
Chapter 3
Use local checks when the PDF should stay on your device
If the document includes contracts, applications, finance records, or anything else you would rather not bounce through another upload-first site, a local size check is a cleaner first step. PDFTry reads the file in the browser, creates a small report locally, and lets you decide whether the next move should still happen in the tab.
Chapter 4
The best email outcome is often a smaller and cleaner PDF
When a PDF is too large, the answer is not always blind compression. Sometimes the better fix is removing blank scans, duplicate pages, or instructions that do not belong in the final handoff. That keeps the document easier to send and easier for the recipient to understand.
Common scenarios
Where this workflow usually shows up.
Job applications and intake portals
Check whether the final resume, cover letter packet, or form attachment is likely to fit before you start a rushed round of last-minute edits.
Client and internal email handoffs
Use a size check before sending contracts, invoices, reports, or review copies so the file does not bounce at the attachment step.
Scanned packets that grew larger than expected
A quick local report tells you whether the scan is ready to send or whether you should compress it or remove extra pages first.

How do I check PDF size before emailing it?
Use a local file-size check before you attach the PDF. PDFTry reads the file in your browser and reports the size and page count without sending the document away first.
What if the PDF is too large for email?
If the file is too large, the next practical fixes are usually compressing it, deleting pages you do not need to send, or splitting the document into smaller parts.
Why not just wait for the email client to reject it?
Because that rejection usually happens at the end of the workflow. Checking the size first lets you fix the document earlier and with less friction.

FAQ
Check PDF size before emailing questions
Can I check PDF size without uploading the file?
Yes. PDFTry's Check PDF Size route reads the PDF locally in your browser and creates a small TXT report without sending the original file to PDFTry first.
Does the size-check tool tell me the recipient's exact limit?
No. It reports the file size your browser sees. You still need to compare that number against the mailbox, portal, or recipient limit you are working with.
What should I do if the PDF is only slightly too large?
Start with compression, then review whether any blank, duplicate, or unnecessary pages can be removed to keep the final handoff cleaner.
When is splitting the better option?
Splitting is useful when the document contains distinct sections or the recipient can reasonably receive more than one attachment instead of one oversized file.
