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
How do I know what X/Y/Width/Height to enter?
X and Y are the pixel coordinates of the crop area's top-left corner (0,0 is the image's own top-left corner); Width and Height are the size of the area to keep, both measured in the original image's pixels.
Can I preview the crop before running it?
Not as a live visual preview in this version — the original image's dimensions are shown so you can calculate the right values, then check the result after running.
What happens if my numbers go outside the image?
You'll get a clear error rather than a broken or blank result — the crop area has to fit entirely within the original image's dimensions.
Does cropping reduce quality?
No — the kept area is copied at its original resolution, not resampled or recompressed beyond the output format's own encoding.
What output format do I get?
The same format as your input — PNG stays PNG (with transparency preserved), JPG stays JPG.
Can I crop to a specific aspect ratio, like square?
Yes — just make Width and Height equal for a square crop, or set whatever ratio you need; there's no preset shortcut, but the math is direct.
Is there a minimum crop size?
Width and Height each need to be at least 1 pixel — anything larger works.
Is my image uploaded anywhere?
No — cropping happens entirely in your browser using the Canvas API; 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 Image Cropper
- Isolate a subject from a larger photo.
- Remove unwanted edges or borders from a screenshot.
- Prepare an exact-size image for a specific placement.
- Cut a section out of a diagram or chart to use on its own.
How it works
Cropping draws just the selected rectangle of the source image onto a new canvas at the coordinates you specify, then exports that as the result — a direct pixel-region extraction, not a visual overlay. The X and Y values are measured from the top-left corner of the original image.
Finding the right coordinates
The tool shows the original image's full dimensions once it loads, which is the easiest reference point for estimating where your crop area should start and how large it should be, especially if you're cropping a specific known region like a logo or a chart within a larger screenshot.
Why people search for Image Cropper
Crop an image to the exact area you want. If you arrived from a comparison article, Image Cropper is the working utility those guides point at: labeled options, local processing, and a download you can verify.
Image Cropper sits in our Image 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 Image Cropper is for
- The file or text is sensitive enough that uploading feels wrong.
- A desktop suite is overkill for a one-page or one-photo job.
- You want a second opinion after another converter produced a weird output.
- You need a result now and do not want another account wall.
Recommended workflow
Start from the highest-quality source → apply one transform → compare before/after → export the format your destination actually needs.
- Open Image Cropper (also available from category hubs and ⌘K).
- Use the labeled fields or dropzone — options match what Image Cropper 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
- 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.
- 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.
Common mistakes with Image Cropper
- Expecting Image Cropper 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 Image Cropper 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.

FAQ — Image Cropper
Is Image Cropper free to use?
Yes. Image Cropper on TechDriven Tools is free — no account, no watermark, and no paywall for the core workflow.
Does Image Cropper upload my file or text?
No for processing. Image Cropper runs in your browser tab. Optional sign-in never stores file contents — only tool names and timestamps if you enable history.
When should I use Image Cropper?
Use Image Cropper for Image Tools jobs where privacy and speed matter: quick one-offs, sensitive inputs, or checking another app’s result without another upload site.
Will Image Cropper 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 Image Cropper?
There is no server quota from us. Limits are your device memory, battery, and formats the browser can decode. Image Cropper will not pretend to support server-only Office or cloud-AI pipelines.
How is Image Cropper different from upload-based sites?
Upload converters send your content to someone else’s server. Image Cropper keeps the transform on-device whenever the format allows, which is the safer default for confidential documents, photos, tokens, and configs.
Bottom line
If you need Image Cropper done quickly and privately, start at /image-cropper, run it once on a sample, then process the real input. That is how TechDriven Tools stays competitive: honest capabilities, labeled UI, and content that matches what the tool actually ships.
