How this actually works
Each tool runs entirely with JavaScript already loaded in this page — PDF tools via pdf-lib and pdf.js, image tools via the browser's native Canvas API, and everything else with plain JavaScript. Your files or input are read into browser memory, processed, and handed back as a download or copyable result. This page itself is served by a small Laravel route; Laravel never sees your files either. The only backend in use is Supabase, and only for two optional things: signing in with a magic link, and — only if you're signed in — a log of which tool you ran and when. Honest limits worth knowing: Compress PDF flattens each page to a re-encoded image (great for scans, not ideal if you need selectable text after); HEIC conversion uses a small on-demand converter when the browser cannot decode HEIC natively (Safari often works without it); Fill PDF Form is best-effort for simple AcroForm fields, not a full Adobe Forms replacement; and Word/Excel/PowerPoint ⇄ PDF genuinely needs a server-side engine, so it isn't included — this build only ships tools that can honestly run client-side.
Questions people actually ask
What image formats can I stamp on?
JPG and PNG.
Can I resize and reposition the image first?
Yes — choose one of 5 position presets (the four corners or center) and set its size as a percentage of page width with a slider; there isn't free-drag placement on a live preview.
Can I stamp on every page at once?
Yes — the "Apply to" option lets you stamp all pages, just the first page, or a custom list like "1,3-5".
Does stamping reduce the image's quality?
No — the image is embedded at its native resolution and scaled to the percentage size you choose; it isn't re-compressed.
Can I stamp more than one image in separate runs?
Yes — run the tool once per image, using the result of one run as the input to the next.
What's the difference between this and Watermark PDF?
Watermark PDF is built for text or logo overlays across many pages with opacity, rotation, and tiling controls. This tool is a simpler, single-image stamp at a chosen position and size — use Watermark PDF if you need opacity/rotation/tiling, and this one for a straightforward logo or image placement.
Can I target specific pages beyond just "all" or "first"?
Yes — the Custom option accepts page ranges like "1,3-5" for exactly the pages you want.
Is the image uploaded anywhere?
No — it's read directly into your browser and embedded into the PDF using pdf-lib; nothing is uploaded.
Is this really free, and is there a file size limit?
Yes — no account, no paywall. Since processing happens in your browser's memory rather than uploading anywhere, the practical limit is your device's available RAM, not a server quota. Very large files (500+ pages) may run slower, especially for Compress and PDF→JPG.
Does anything about my file get sent anywhere?
No. Every tool runs with pdf-lib/pdf.js loaded in this page; your file is read into browser memory and never leaves it. The only network call this app makes for your account is Supabase auth — and that only stores which tool you ran and when, never file content.
Why isn't Word/Excel/PowerPoint → PDF included?
Converting Office formats accurately needs a real rendering engine (what Word or LibreOffice use internally) — no browser library does this reliably. Rather than ship a broken version, it's left out.
Does TechDriven Tools have OCR (text recognition)?
Yes — OCR PDF recognizes text in scanned or photographed pages using Tesseract.js, running entirely on your device, and gives you a searchable PDF or a plain text file. Nothing is uploaded for this either.
Can I use this without an internet connection?
Once the page and its libraries have loaded once, yes — the tools themselves need no network access. Signing in and viewing history do require a connection, since those talk to Supabase.
What happens to the "history" if I sign in?
Only a row per tool run — the tool's name and a timestamp. No filename, no file content, ever. You can see the full list any time via the History button.
Are the non-PDF utilities (password generator, JSON formatter, etc.) private too?
Yes — same rule as the PDF tools. Word Counter, Case Converter, Password Generator, UUID Generator, Base64, Hash Generator, JSON Formatter and JWT Decoder all run with plain JavaScript already loaded in this page; nothing you type or paste is sent anywhere.

Why use Add Image to PDF
- Add a company logo to an official document or letterhead.
- Place a scanned signature onto a contract or form.
- Stamp a "Received" or "Approved" mark onto a processed document.
- Add a photo or diagram directly onto a specific page.
How it works
The image you upload is embedded directly into the PDF page via pdf-lib and positioned using the preset (or size) you choose — it becomes a real part of the page content, not an overlay added by a viewer. This means the stamp is visible in any PDF reader, not just this tool.
Add Image to PDF vs. Sign PDF
For a hand-drawn signature specifically, Sign PDF is purpose-built — it gives you a drawing canvas rather than requiring a pre-made image file. Use this tool when you already have an image (a logo, a scanned stamp, a photo) ready to place, and Sign PDF when you want to draw a signature fresh.
Why people search for Add Image to PDF
Stamp a logo, photo, or scanned signature onto any page. For teams, share the link instead of emailing binaries of desktop installers — everyone gets the same Add Image to PDF behavior in a modern browser.
Add Image to PDF sits in our PDF Tools group. The page is built so you can finish the job without creating an account, installing a desktop pack, or sending the payload to an unknown converter API.
Who Add Image to PDF is for
- You want a second opinion after another converter produced a weird output.
- You need a result now and do not want another account wall.
- The file or text is sensitive enough that uploading feels wrong.
- A desktop suite is overkill for a one-page or one-photo job.
Recommended workflow
Add unlocked PDFs → set order or ranges → run → open the download and spot-check first, middle, and last pages.
- Open Add Image to PDF (also available from category hubs and ⌘K).
- Use the labeled fields or dropzone — options match what Add Image to PDF actually does.
- Run the tool and wait for local progress to finish.
- Download or copy the result, then verify on the device where you will share it.
Tips that improve results
- Start with a non-sensitive sample so you learn the options before the real file.
- Change one setting at a time when you are comparing quality or layout.
- Keep the original until stakeholders accept the download.
- Rename the output with date + purpose before you attach it to email.
- On phones, plug in power for large PDFs, videos, or spreadsheets.
- Prefer UTF-8 text for developer converters; weird encodings cause most “broken” results.
Common mistakes with Add Image to PDF
- Expecting Add Image to PDF to replace a full desktop suite for every edge-case format.
- Skipping a sample check and discovering a bad export after the original was deleted.
- Chaining many lossy image/PDF steps when one careful pass would have been enough.
- Using a public computer without clearing downloads afterward.
Privacy model
Processing for Add Image to PDF is designed to stay in the browser. Laravel serves the page; it does not receive your file bytes for conversion. Optional Supabase auth only stores which tool you ran and when — never filenames or contents.

Use Add Image to PDF for PDF Tools jobs where privacy and speed matter: quick one-offs, sensitive inputs, or checking another app’s result without another upload site.
Will Add Image to PDF work on my phone?
Yes in a modern mobile browser. Large inputs can take longer because your device does the work locally.
What are the limits of Add Image to PDF?
There is no server quota from us. Limits are your device memory, battery, and formats the browser can decode. Add Image to PDF will not pretend to support server-only Office or cloud-AI pipelines.
How is Add Image to PDF different from upload-based sites?
Upload converters send your content to someone else’s server. Add Image to PDF keeps the transform on-device whenever the format allows, which is the safer default for confidential documents, photos, tokens, and configs.
