How Dekiko works

Other sites send your file to their servers. Dekiko brings the tool to your file instead.

Choose your file
Your browser opens it from your phone or computer. It is not uploaded anywhere.
Set it up
Reorder pages, pick a size, or type a watermark. You see every page before anything changes.
Download the result
The new file is made on your device in seconds and saved straight to your downloads.

Want proof? Add a file, switch off Wi-Fi and mobile data, then run the tool. It still works. How we protect your files

What people use Dekiko for

Exam, job and admission forms

Portals often accept only one PDF under a strict size. Turn photos of certificates into one PDF, then bring it under the limit.

JPG to PDF Merge PDF Compress to 100KB

KYC and ID copies

When a bank or landlord asks for a copy of your ID, stamp it with what it is for. A copy marked "Only for XYZ KYC" is much harder to misuse.

Add watermark Extract pages

Office and small business

Join a month of invoices into one file for your accountant, number the pages of a report, or send only the pages someone needs.

Merge PDF Page numbers Split PDF

Students and teachers

Fix scanned notes that came out sideways, put chapters in order, or turn a slide PDF into images to share in a class group.

Getting a PDF under an upload limit

A PDF's size depends far more on what is inside it than on how many pages it has. A typed letter is tiny; the same letter photographed with a phone can be a hundred times bigger, because every page is now a detailed picture.

Before you scan

Scan documents at 150 to 200 DPI. Higher settings mostly add size, not readability.
Choose grey or black and white for text. Colour can triple the size.
Crop away the table or bedsheet around the page when you take a photo.

After you scan

Remove blank or extra pages first. Every page you drop is size you do not need to compress.
Then compress to the exact limit, and open the result to check it is still readable before you upload.
If a long document will not fit, split it into parts, if the portal allows more than one file.

Rough size of one PDF page
What the page is	Usual size	What to do
Typed document saved as PDF (from Word, Docs)	5 to 50 KB	Already small. Light compression is enough.
Scanned page, black and white or grey, 150 DPI	50 to 150 KB	Usually fits a 100 to 200 KB limit per page.
Scanned page in colour, 300 DPI	300 KB to 1 MB	Compress, or rescan at a lower DPI in grey.
Phone photo turned into a PDF page	1 to 4 MB	Compress to a target size before uploading.

Sizes vary with the scanner, the camera and how busy the page is. Treat them as a starting point.

PDF words, explained simply

PDF: Portable Document Format. A file that looks the same on every phone, computer and printer, which is why forms and offices ask for it.
KB and MB: Units of file size. 1 MB is 1,000 KB. Some websites count 1,024 KB per MB, so Dekiko aims slightly under any limit you set.
DPI: Dots per inch: how much detail a scan or image holds. 150 DPI is sharp enough for most documents; 300 DPI is print quality and much bigger.
Lossless compression: Makes a file smaller without changing anything you can see, by removing waste inside the file. Savings are usually small.
Lossy compression: Makes a file much smaller by lowering image quality slightly. Pages are saved as pictures, so text can no longer be selected.
Page rotation: A setting inside a PDF that tells readers how to turn a page. Rotating fixes it permanently, in every PDF reader.
Watermark: Text stamped across a page, such as "COPY" or "CONFIDENTIAL", to show how a document may be used.
ZIP file: One file that holds several others. When a tool makes many files, you download them together as a ZIP.

Questions people ask

Is Dekiko really free?

Yes. Every tool is free, with no account, no daily limit and no watermark added to your files.

Is it safe to use for Aadhaar, PAN or bank statements?

Yes. Your files are processed inside your own browser and are never uploaded, so they do not reach us or anyone else. You can even turn off the internet after adding your file and the tool still works.

Does it work on my phone?

Yes. Dekiko is built for phones first and works in Chrome, Safari, Edge, Firefox and Samsung Internet. You can also add it to your home screen like an app.

Is there a file size limit?

There is no fixed limit. Because the work happens on your device, very large files depend on how much memory your phone or computer has.

Why can I not select text after compressing?

Strong compression saves each page as an image, which is what makes big savings possible. If you need selectable text, choose the "Light" level in Compress PDF.

Which tool should I use to get under an upload limit?

Use Compress PDF to 100KB, 200KB, 500KB or 1MB. You can also type any size you need in the target box.
