EveryPDFToolHow to Reduce a PDF Under 10 MB in 2026
Getting below a specific upload limit is different from simply making a PDF smaller. First measure how much reduction you actually need, then use the least destructive method that gets the file comfortably below 10 MB.
Quick answer
Check the current file size with PDF Size Analyzer. Remove unnecessary or blank pages first, then use Compress PDF. If the document still cannot reach the target without becoming hard to read, split it only when the receiving system allows multiple files.
Reviewed: October 2026Step 1: calculate how much reduction you need
The starting size determines how aggressive the process needs to be. A 10.5 MB PDF only needs a small reduction, while a 40 MB scan must lose most of its size.
| Starting size | Approximate reduction needed to get below 10 MB |
|---|---|
| 12 MB | More than 16.7% |
| 15 MB | More than 33.3% |
| 18 MB | More than 44.4% |
| 25 MB | More than 60% |
| 40 MB | More than 75% |
Do not aim for exactly 10.00 MB. Upload systems can calculate limits differently and may add their own processing overhead, so leave some margin below the stated maximum.
Step 2: inspect the PDF before compressing it
Use PDF Size Analyzer to confirm the total file size, page count and average size per page. This does not identify every individual object inside the PDF, but it quickly tells you whether the document is unusually large for its page count.
A two-page PDF that is tens of megabytes is often image-heavy. A very long PDF may simply contain many pages.
Step 3: remove unnecessary pages
Use Remove PDF Pages for pages that are not required. If a scanned document contains accidental empty sheets, use Delete Blank PDF Pages.
This should usually happen before image compression because deleting pages can reduce file size without reducing the visual quality of the pages that remain.
Step 4: compress the PDF once
Use Compress PDF and check the result. EveryPDFTool reports the original size, resulting size and percentage reduction, making it easy to see whether the file has reached the target.
The compressor can downsample stored images and optimize other PDF resources. Image-heavy and scanned PDFs often have more room to shrink than files dominated by text and vector graphics.
How aggressive should compression be?
| Current situation | Suggested approach |
|---|---|
| Only slightly over 10 MB | Start with balanced compression |
| Well above 10 MB and mostly scans/photos | Try stronger compression and inspect readability |
| Fine print or detailed diagrams are important | Favor quality and remove pages before reducing resolution further |
| Already optimized PDF | Expect limited savings from another compression pass |
Why can a two-page PDF be larger than 10 MB?
A PDF page can contain a very large raster image. For example, a high-resolution color scan or photograph may use several megabytes by itself. Two such pages can therefore exceed 10 MB even though the document is short.
Page count is not a reliable measure of file size. Image resolution, image dimensions, compression method, embedded fonts and other stored resources also matter.
What if stronger compression damages readability?
If small text, signatures, identification details, diagrams or photographic evidence become unclear, stop reducing quality simply to meet the number. Remove optional content instead, or use another submission method if the destination allows it.
Use Split PDF only when the destination accepts multiple files
Split PDF can create smaller parts, but this only solves the problem when the receiving website, email system or organization accepts the document in multiple files. If the portal explicitly requires one PDF under 10 MB, splitting does not satisfy that requirement.
Why repeated compression is usually a poor strategy
Compressing an already compressed PDF again may produce diminishing size savings while repeatedly downsampling images. It is usually better to assess the result after one pass and then change strategy: remove pages, choose a stronger setting once, or reconsider the source scans.
A practical under-10-MB workflow
| Step | Action | Purpose |
|---|---|---|
| 1 | Analyze size | Measure how much reduction is required |
| 2 | Remove extras | Reduce size without lowering page quality |
| 3 | Delete blank pages | Clean unnecessary scan output |
| 4 | Compress PDF | Reduce image and PDF resource size |
| 5 | Check readability and final size | Confirm the PDF is usable and below the target |
| 6 | Split only if permitted | Create smaller parts when one-file submission is not required |
Frequently asked questions
Can every PDF be compressed below 10 MB?
No. Some documents contain too much required image or page data to reach that size without unacceptable quality loss. The achievable reduction depends on what is stored inside the PDF.
How much do I need to compress a 20 MB PDF to get below 10 MB?
You need a reduction of more than 50 percent. Leave some additional margin below 10 MB rather than targeting the limit exactly.
Why is my two-page PDF larger than 10 MB?
The pages may contain high-resolution scans or photographs. A short image-heavy PDF can be much larger than a long text-based document.
Should I compress a PDF several times?
Usually not. Repeated compression can provide diminishing savings while reducing the quality of scanned text and images.
Will splitting a PDF solve a 10 MB upload limit?
Only if the destination accepts multiple files. If it requires one PDF below 10 MB, the final single PDF still needs to meet that limit.
