What fits in 2 MB
| Your PDF | Usual outcome at 2 MB |
|---|---|
| Most typed documents and exported presentations | Already under 2 MB, or fits in Stage A |
| Theses, portfolios and reports with images | Usually fits in Stage A or B |
| Up to about 40 scanned grayscale pages | Usually fits in Stage B |
| Hundreds of colour scan pages | Split the document first |
How DocNimble gets a PDF under 2 MB
The compressor works on your device and stops at the first step that reaches 2 MB:
- Already small enough? If the PDF is already at or under 2 MB, you get the original back untouched. Nothing is recompressed for no reason.
- Stage A — lossless clean-up. Unused objects and inefficient structures are removed. Text, images and layout stay exactly the same.
- Stage B — image recompression. Photos and scans inside the PDF are re-encoded at the highest JPEG quality that fits. The text layer is kept, so words stay selectable and searchable.
- Stage C — page images (only if you allow it). When A and B are not enough, ticking the rasterise option turns each page into an image at a progressively smaller size. This reaches small targets, but the text is no longer selectable, so check readability before you submit.
The tool reports the real size of the downloaded file. It only says “target achieved” when the measured bytes are at or under the limit; otherwise it gives you the smallest result it reached and says so.
Change as little as possible
With a 2 MB budget, the lossless Stage A is often enough on its own: the file gets smaller and nothing you can see changes. If Stage B is needed, it re-encodes images at the highest quality that fits, so photos usually look unchanged at normal zoom. Leave the page-image option off unless the file genuinely cannot reach 2 MB another way.
Digitally signed PDFs: compress with care
Any tool that rewrites a PDF — compression included — invalidates a digital signature, even though the page looks identical. If your document was digitally signed by an authority (for example an e-certificate or a DSC-signed form) and the receiver checks that signature, upload the original instead, or ask the issuer for a smaller signed copy. Read more in what happens to PDF digital signatures after editing.
Other ways to get under 2 MB
- Remove appendices or duplicate pages with Remove PDF pages.
- Split a very long document into parts with Split PDF.
- For many photos, shrink them first with Compress Image, then combine with JPG to PDF.
Check before you upload
- Confirm the size and that the page count is unchanged.
- Try selecting text to confirm it is still searchable.
- If the receiver validates a digital signature, send the original signed file instead.
Questions about this workflow
Will compressing to 2 MB reduce quality?
Often not at all: lossless Stage A alone usually gets there. If images must be re-encoded, the tool uses the highest quality that fits.
Does compression break a digital signature?
Yes. Any rewrite of a signed PDF invalidates the signature. If the signature will be checked, upload the original signed file.
Can I compress several PDFs into one 2 MB file?
Combine them with Merge PDF first, then compress the merged file once.
Is there a file size limit for the input?
There is no fixed limit, but very large PDFs need more memory and time, especially on phones.
