Upload Limit Checker

Calculate exactly how much you need to shrink a file (e.g., from 12.4 MB to 2 MB) before you compress or split.

Privacy-first processing

Where supported, tools run locally in your browser. Your files are not uploaded to our servers from these pages.

Some tools may rely on third-party libraries loaded from CDNs; review your browser settings and our privacy policy for details.

Start with these common workflows

If you are not sure which tool to use, pick a workflow below and follow the steps. These are the scenarios we see most: uploads to portals, email attachments, and preparing clean files for printing.

1) “My PDF is too large to upload” → Compress PDF → if still large, try Extract pages to submit only the required pages.

2) “I must send multiple PDFs as one file” → Merge PDF → then Add page numbers for long packets.

3) “I need text from a PDF” → Extract text → or open PDF to Word (DOCX) on the PDF Tools page.

4) “My image is too big for a form” → Image tools → crop first, then compress for best quality.

How to choose the right tool (quick guide)

Compression reduces file size. It is best when you must meet a limit (e.g., 2MB / 10MB).

Conversion changes format (e.g., JPG→PDF). Do this when a portal requires a specific type.

Editing changes the document structure (merge/split/reorder/delete pages). Do this when the recipient needs fewer pages or a specific order.

Tip: A scanned PDF behaves like a stack of images. For the biggest savings, reduce scan resolution at the source (scanner/export settings) and only then compress.

For detailed guidance, see: PDF size limits and how to compress without blur.

Quality and transparency

Each tool page explains what it does, what it cannot do, and how your file is handled. If a workflow requires a specific browser capability or third-party library, that is stated on the page. This helps you make an informed choice before you process documents.

If you discover a broken link or a tool that does not behave as described, please report it via Contact with the exact URL and your browser version.

Compress It Small is built to help you pass strict file upload limits with a clean user experience. Most tools run locally in your browser when technically possible.

Recommended workflow

  1. Check the limit with Upload Limit Checker.
  2. Reduce content first (remove/extract pages, crop images).
  3. Compress last to keep quality readable.
  4. Verify the final size.

All Free Online File Tools — Privacy-First, No Upload Required

Every tool on this site runs inside your browser. Your files are processed locally — they are never uploaded to our servers, never stored in a database, and never accessible to anyone except you. Close the browser tab and all traces of your file disappear from memory automatically.

PDF tools

The most-used category: compress, merge, split, rotate, extract pages, delete pages, reorder pages, add page numbers, watermark, and redact. Also convert between formats: PDF to JPG, PDF to PNG, JPG to PDF, and extract text from PDF.

Image tools

Compress, resize, convert, crop, and watermark images — JPG, PNG, and WEBP all supported.

Office and data tools

Convert between office formats: text to DOCX, text to PDF, Excel to CSV, CSV to Excel, CSV to JSON, JSON to CSV, and format/validate JSON.

Built for real submission and upload workflows

These tools exist because file size limits, format requirements, and portal restrictions are genuine friction points — in PhD applications, visa submissions, job applications, scholarship forms, and everyday document sharing. Each tool is designed for the specific task it performs, with clear outputs and no unnecessary steps. If a task cannot be done reliably in-browser, the tool will say so explicitly rather than produce unreliable results.
