SiapinData.com is a collection of free online PDF and photo tools for users in Southeast Asia, including a document readiness checker and PDF page organizer. All files are processed directly in the browser — not uploaded to the server — so they are suitable for personal documents such as KTPs, diplomas, transcripts, CVs and formal CPNS photos.

No additional sign-ups, subscriptions or apps required. Open the tool, select a file, then download the result.
Ready for CPNS & applications
Target photo 100 KB, crop 3:4, PDF maximum 1–2 MB, as well as ZIP bundles for multiple files.
How to use: maximum three steps

- Select files. PDF, JPG, PNG, and WebP formats according to tool type. Maximum 20–30 files per batch.

Frequently asked questions about SiapinData
Are my files uploaded to the server?
No. SiapinData.com processes files directly in the browser using JavaScript, canvas, pdf-lib, and pdf.js. Your files are never sent to the SiapinData.com server.
Is SiapinData.com free and does it require an account?
SiapinData.com is free and without an account. You can immediately open the tool you need, select the file, then download the results.
What file formats are supported?
SiapinData supports PDF, JPG/JPEG, PNG, and WebP. Some tools limit the number of files, for example 20 photos at a time or 30 images to make a PDF.
How do I reduce photos to 100 KB for CPNS?
Open the Reduce Photo tool, select the 100 KB (CPNS) preset, then select the photo. SiapinData will reduce the quality and resolution gradually until it approaches the target. For formal photos, use Crop to Ratio 3:4 before or after.
Can PDF text still be selected after compressing?
Light and Medium modes preserve PDF text. Strong Mode converts the page to a JPEG image, so the size is smaller but text cannot be selected.
Can SiapinData be used on a cellphone?
Yes. The SiapinData display is responsive for cellphones and tablets, and supports individual and ZIP downloads in modern browsers such as Chrome, Safari, Edge, and Firefox.
What if the PDF is password locked?
Password protected PDFs cannot be processed. Delete or unlock the PDF password first, then re-upload the unlocked file.
Does processing history save file contents?
No. History only stores metadata such as file names, before and after sizes, tools used, and processing time in your device's localStorage. The contents of the file are not saved.
How do I check CPNS documents before uploading?
Open Document Check, select CPNS/SSCASN, then add the file and determine the type. SiapinData checks size, 3:4 photo ratio, format, number of pages, and unreadable files. All checks run in the browser.
Can I change the page order of a PDF?
Yes. Go to Arrange PDF Pages, select the PDF, then use the up, down, rotate, or delete buttons. Once finished, download a new PDF with the page order already arranged.

Privacy & Security
Overview of how SiapinData.com handles files, local data and advertising.
Your files stay on the device
PDF files and images are processed directly in the browser using libraries loaded from this domain. We do not upload, store or send file contents to the server. The compression, merge, split, crop and conversion processes are carried out in your device's memory.
History and preferences
SiapinData only stores historical metadata on localStorage: file name, before/after size, tools used, and processing time. The contents of the file are not saved. Light/dark themes are also saved as local preferences. You can delete your history at any time from the History page.
Advertising and third party cookies
This site uses Google AdSense to display advertisements. Google and its partners may use cookies, device IDs or similar technologies to serve ads, limit the frequency and measure the performance of ads. The files you process are not provided to advertisers.
You can set your Google advertising preferences via Google Ads Settings and read Google advertising policies. In regions where it is mandatory, Google may request consent before using advertising cookies.
Analytics
Cloudflare Web Analytics can record aggregate visit statistics without accessing the contents of the files. No analytics accepts user files.
External link
Links to Trakteer, Google and other sites will lead to third party sites with their respective privacy policies. SiapinData does not send files to those links.
