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 depends on your browser (Safari usually works; Chrome often cannot decode HEIC without a library we don't ship); 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 template does it produce?
A single clean, ATS-friendly layout — name and contact details at the top, then summary, experience, education, and skills sections in order.
Can I add or remove sections/entries?
Yes — "+ Add" buttons add as many experience or education entries as you need, each with its own remove button.
Does it use AI to write my content?
No — you write your own summary and experience descriptions; nothing here generates or suggests wording for you.
Is there a page limit?
No hard limit is enforced, but a resume that runs long naturally splits across multiple PDF pages — for a traditional one-page resume, keep entries concise.
Does it save my information anywhere?
No — nothing is stored. Download the PDF when you're done; re-open this tool and re-fill the form if you need to make a change later.
Can I use this for a CV instead of a resume?
The same experience/education/skills structure works for a longer CV — just add more entries; there's no length restriction.
What file format does it download as?
A PDF, generated entirely in your browser using pdf-lib.
Is my personal information sent anywhere?
No — nothing you type ever leaves your browser.
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.
Resume Builder, in depth
Resume Builder helps assemble a clean PDF resume with structured sections — private drafting before you apply.
How Resume Builder works here
Resume Builder runs locally in your browser on TechDriven Tools. Inputs stay on your device — nothing is uploaded for this step.
Read every label before running. For Resume Builder, the controls that change outcomes most are: sections for experience/education/skills, PDF export. Change one control at a time when you are comparing results.
When to use it
Use Resume Builder when the job matches what the tool is named for — not as a generic substitute for unrelated PDF or data tasks.
Prefer this browser version when the input is sensitive and you want processing to stay on-device with clear option names like: sections for experience/education/skills, PDF export.
If the next step differs (for example you finished and now need a sibling utility), jump to a related tool instead of forcing one screen to do everything.
Teams standardize on Resume Builder when the alternative is emailing files to a consumer upload site. Document the preferred option defaults (for example the usual quality, corner, or rate) so everyone reproduces the same result.
If Resume Builder is only one step in a pipeline, write the order down: what happens before, what happens after, and which related tool owns each step. That prevents double-processing and accidental quality loss.
On mobile, prefer moderate file sizes and simpler option combinations. Local processing is powerful, but phones have less memory than desktops for huge scans or megapixel images.
Draft a clean PDF CV. Structure experience and skills without a desktop publisher.
Iterate privately. Edit locally before uploading to job boards.
Export for ATS-friendly text. Keep layout simple so parsers survive.
Options that change the result
Primary controls
The important controls are: sections for experience/education/skills, PDF export. Change one at a time when comparing outcomes so you know what improved the result.
Run and verify
After you run Resume Builder, open or inspect the output on the device where you will share it. Keep originals until that check passes.
Boundaries
This page does not replace desktop suites for heavy Office conversion or certified legal e-sign. It covers the focused job described above.
Practical defaults
Start with conservative defaults on Resume Builder, run once, then adjust. Extreme settings (lowest quality, highest tip, densest QR payload) are for known constraints — not first tries.
Inputs that surprise people
People often misread units or page indexes. Align with the on-screen labels and the total page count or unit selectors before blaming the engine.
Outputs and naming
Rename downloads immediately (date + client + purpose). Resume Builder may use a generic filename; clear names prevent sending yesterday’s draft.
Accessibility and sharing
After visual tools (watermark/sign/page numbers), skim a page with fresh eyes for contrast and coverage. After data tools, copy results into the system of record your team actually uses.
Privacy
Resume Builder is designed to run in your browser so your files and text are not uploaded for the core transformation.
Still handle downloads carefully: a private process can still leave sensitive files in your Downloads folder.
Optional accounts on TechDriven Tools, when used, are about lightweight usage metadata — not storing the contents of your Resume Builder inputs.
If policy requires a vendor DPIA for any online tool, note that local browser processing reduces data transfer risk, but downloaded artifacts still need handling under your retention rules.
Resume Builder is built to process locally in your browser so sensitive PDFs, images, or text do not need to be uploaded to an unknown server just to finish this job.
Common mistakes
- Tiny unreadable fonts to fit everything — ATS and humans both suffer — edit ruthlessly.
- Graphics-heavy layouts — Parsers stumble on text-in-images.
- Lying for keywords — ATS Checker helps coverage; inventing experience backfires in interviews.
Getting reliable results from Resume Builder
Most failures with Resume Builder are input/setting issues rather than mysterious bugs: wrong units, wrong page lists, wrong language, or expecting one tool to do a sibling’s job. Re-read the option names, fix the input, and re-run — local tools make iteration cheap.
Resume Builder accelerates the workflow; it does not replace your judgment or professional advice where required.
Related tools
These related tools commonly sit before or after Resume Builder in real workflows.
- ATS Resume Checker — Compare your resume against a job description and see which keywords are missing.
- Invoice Generator — Fill in a simple form and generate a clean, downloadable PDF invoice.
- Word Counter — Count words, characters, sentences and paragraphs as you type.
Use Resume Builder when you need this specific job done privately and quickly. Respect what it is not (see mistakes), verify outputs, and chain related tools only when the next step truly differs.
