Why 1 MB Is the Magic Number
Government portals across India — scholarship applications, job portals, university admissions — frequently set a 1 MB or 500 KB file size limit per document. This is frustrating when your scanned certificate is 8 MB or your application PDF is 15 MB. But it is solvable.
Step 1: Use PDF Compression First
- Go to iloveconvert.in/compress-pdf
- Upload your PDF
- Click Compress PDF
- Download and check the new size
For most scanned documents, this alone brings the file under 1 MB. Text-based PDFs (created from Word) often compress to under 200 KB.
Step 2: If Still Over 1 MB — Reduce Image Quality
If your PDF contains high-resolution scanned pages, the images inside the PDF are the main size contributor. The compression tool reduces these automatically, but very high-DPI scans may need extra steps.
Try this: Print the PDF to a new PDF (Ctrl+P → Save as PDF in Chrome) — this flattens and recompresses images at screen resolution, typically reducing size dramatically.
Step 3: Split and Submit Separately
If a single document must stay under 1 MB but contains many pages:
- Use Split PDF to separate into individual pages
- Upload each page or small group of pages separately if the portal allows
- Or merge only the essential pages (removing blank pages and unnecessary content)
Step 4: Convert to Grayscale
Color PDFs are significantly larger than grayscale. For certificates, marksheets, and most official documents where color is not required, converting to grayscale reduces size by 50–70%.

- Signature: Under 50 KB (JPG)
- Aadhaar / ID scan: Under 200 KB (PDF)
- Marksheet: Under 500 KB (PDF)
- Full application bundle: Under 2 MB (PDF)
