Shrink a heavy PDF to fit email attachments and portal caps like 2 MB. See what makes PDFs large and pick a compression level that keeps text readable.
A ten-page PDF typed in Word might weigh 200 KB. The same ten pages scanned on a phone can top 20 MB. The difference is almost always images. Text is stored as compact instructions, while a scanned page is one big photograph. A PDF compressor works mainly by shrinking those images.
Compression tackles these roughly in order of impact. Images are usually downsampled to a lower resolution and recompressed. Duplicate fonts and unused objects can be stripped out. On a scanned file, the image step does almost all the work.
Say you scanned twelve pages of property documents for a bank portal with a 2 MB cap. Here is a sensible sequence.
Results vary with content. Pages packed with colour photos shrink less predictably than black and white text scans.
| Level | Best for | Trade-off |
|---|---|---|
| Low | Print-ready brochures, design proofs | Modest savings, images stay crisp |
| Medium | Email attachments, sharing with clients | A good balance for most documents |
| Strong | Portal uploads with strict KB or MB caps | Images soften, fine print may blur |
Gmail caps attachments at 25 MB, and many job and government portals allow far less. Choose the lightest level that gets you under the limit.
A quick test saves embarrassment. Compress a two-page sample first, then read it on a phone screen. If it reads well there, the full document will too.
Sensitive files such as ID proofs, bank statements and salary slips deserve extra care. Read how any online tool, ToolsMate included, handles uploaded files before you use it. Remove pages you do not need to share before compressing. A smaller document is both lighter and safer to send.

Use the strongest compression setting and check whether the result fits. Scanned files may still be too large, so rescan in greyscale at about 150 DPI. Removing unnecessary pages also helps. Very image-heavy documents sometimes cannot reach 200 KB while staying readable.
It mostly reduces image quality, not text quality. Typed text stays sharp because it is stored as vector data. Photos, scanned pages and stamps may soften, so always zoom in and check important details before sending the compressed file.
The file probably contains mostly text, vector graphics or images that were already compressed. There is little left to remove. Large size in a text-based PDF often comes from embedded fonts or attachments, which basic compression may not touch.
Usually you need to remove the password first, because the compressor cannot read encrypted content. Open the file with the password, save an unprotected copy and compress it. Add protection again afterwards if the recipient requires it.
Yes, it can. Any change to a digitally signed PDF typically invalidates the signature check. If a document carries a DSC or Aadhaar eSign, send it unmodified. Alternatively, ask the signer to sign the compressed version instead.
It can be, but first check the tool's privacy policy for how uploads are stored and deleted. Avoid public or shared computers for this task. For highly sensitive files, an offline PDF application on your own device is the safer choice.
For text documents, 150 to 200 DPI in greyscale gives clear reading with small files. Use 300 DPI only for documents that will be printed or need fine detail. Higher scan resolution makes compression work harder and leaves larger files.
