From a free tool to your own software

Mobile apps for teams that report and claim with photos

Site engineers, store auditors and sales staff document their work with phone photos, which then sit in chat groups until someone turns them into a report. Photos get lost, dates get mixed up, and managers receive a string of images instead of something they can file or forward. A purpose-built app captures photos inside a structured form and produces a clean, dated document the moment the job is done.

  • Construction site progress reporting

    Engineers log daily progress with photos tagged to the project, floor and activity, and the app produces a dated daily report the client and head office can both open.

  • Expense and reimbursement apps

    Staff photograph bills on the spot, add the amount and purpose, and a claim document goes to the approver with every receipt attached, ready for accounts to process.

  • Store and vehicle inspection checklists

    Auditors work through a checklist on their phone, attach photo evidence to each item, and the finished inspection is saved as a report with scores and follow-up actions.

  • Warranty and service claim intake

    Customers photograph their invoice, serial number and the fault, and your service team receives a single claim document instead of scattered images across email and chat.

Who we build this for: Construction firms, retail chains, fleet operators, field sales teams and consumer brands handling service claims.

This tool runs entirely in your browser. The team that built it designs custom software for businesses and runs DigiSign, our own signage platform, in production.

Questions people ask

How do I convert JPG to PDF for free?

Drop your images here, pick a page size, and download — free with no watermark, no signup and no page limit.

Can I combine multiple photos into one PDF?

Yes — add as many images as you like and drag them into order; each becomes one page of the PDF.

How do I convert a photo to PDF on my phone?

Open this page, tap the drop area to pick photos from your gallery, and convert — the tool is built mobile-first, and sideways phone photos are straightened automatically using their rotation data.

What page size should I choose?

A4 for documents and government portal uploads in India, Letter for US paperwork, and "Fit to image" when the PDF page should match the photo's own dimensions exactly.

Does converting reduce photo quality?

JPG and PNG files embed losslessly — the very bytes of your image go into the PDF. Only formats PDF cannot hold natively (like WebP) are re-encoded, at high quality.

Are my photos uploaded?

No — the PDF is built on your device. Photos of ID cards, signatures and certificates never leave your phone, which is the whole point of doing it in the browser.

What about HEIC photos from an iPhone?

Most browsers cannot decode HEIC, so the tool tells you clearly instead of producing a broken page — convert them to JPG first, then add them here.
