How NOT to create MP3 music from cassette (Feat. Techmoan)

DVD and Audio Backups Ahoy!

Waiting for DVDs to convert to AVI as backups is a pain in the backside no matter what program I’m using to get it done, but well worth it for folks like me who like to collect physical media but want to preserve it and avoid damaging discs or cases. Not to mention running DVDs on a laptop means accessing menus is a tedious affair that I really don’t enjoy doing. Patience, as they say, is a virtue.

It turns out that ripping from AAX and converting from M4B to MP3 is much less time consuming despite there being a lot more typing involved.

I got a lot done today (and will be getting others done in the near future) and I’ll have them nestled safely in my Dropbox so that they don’t take up too much space on my laptop.

why won't my iphone photos open on my pc (and how to fix it free)

so you airdropped/emailed/USB'd some photos off your iphone and now your computer just... won't open them. this happens to literally everyone at some point and it's because of a format called HEIC. here's the free fix.

okay but what even is HEIC

it's the format your iphone has been saving photos in by default since iOS 11. the upside: files are like half the size of an equivalent JPG. the downside: basically nothing outside the apple ecosystem knows what to do with it.

windows just... won't preview it

some apps and messengers reject HEIC uploads or mangle the quality converting it themselves

you email/drive-share it to someone and they can't open it, cue the "can you resend as jpg" text

ImageStream's HEIC Converter fixes all of this in your browser, no download required.

free, no account

everything processes locally, nothing gets uploaded

converts to JPG, PNG, or WebP

does up to 20 files at once, zips them up for you

how to actually use it

upload your HEIC files — drag em in, up to 20 at a time

pick your output format. JPG has a quality slider if you want to fine-tune the size/quality tradeoff, PNG is lossless

download — one at a time or all together as a zip

when this actually saves you

windows users who just want the file to open. convert to jpg/png first, skip the whole "why won't this open" spiral entirely.

posting to social media / messaging apps. some silently wreck the quality converting HEIC themselves, or just reject it. converting yourself first = you control the quality.

sending stuff for work. nothing like a HEIC attachment nobody on the other end can open. convert before you send, save everyone the round trip.

quick FAQ

what's a HEIC file, actually? apple's compressed photo format since iOS 11 — about half the size of a same-quality JPG, but compatibility outside apple devices is spotty.

does converting lose quality? converting to jpg can lose a little, but cranking the quality slider up keeps it close to the original. png conversion is lossless.

can I do a bunch at once? yep, up to 20 files, and you get them all back as one zip.

what about live photos / depth data? only the still frame converts — the video part of a live photo doesn't carry over, and depth map metadata gets stripped too.

can I just stop my phone from saving as HEIC? settings > camera > formats > "most compatible" switches it to jpg going forward. files get bigger though, so a lot of people just keep HEIC and convert when they need to.

there's a bunch of other free browser-based image tools over at ImageStream if you're into that — compression, background removal, all no-signup.

need to convert other image formats too? the format converter tool's got you.

Why We Built a Browser-Based File Converter Instead of Another Cloud Service

When we started building applications that handled documents, images, videos, and audio files, we kept running into the same problem.

Almost every file conversion service worked like this:

Upload your file.

Wait while it reaches a remote server.

The server processes it.

Download the converted file.

Hope your file is deleted afterward.

At first, this didn't seem like a big deal. It's how most online converters have worked for years.

But after integrating several of them into our workflow, we started asking ourselves a simple question:

Why does every file have to leave my computer just to change its format?

The Privacy Problem

Imagine converting:

your passport

tax documents

contracts

customer data

private photos

business presentations

Every one of these files is uploaded to someone else's infrastructure.

Most services promise that files are deleted after a few hours.

Some say 24 hours.

Some say 48 hours.

Some don't even mention how long files are stored.

The reality is simple:

If your file reaches a server, you no longer have complete control over it.

Even if the company is trustworthy, uploading sensitive files introduces additional risks that simply don't exist when everything happens locally.

The Performance Problem

Uploading large files is slow.

A 2 GB video doesn't start converting immediately.

First, it needs to be uploaded.

Then processed.

Then downloaded again.

For many users, the upload takes longer than the actual conversion.

If your internet connection is unstable, you start over from scratch.

We thought there had to be a better approach.

Modern Browsers Are More Powerful Than We Think

A few years ago, building a browser-based converter would have sounded unrealistic.

Today, browsers support technologies like:

WebAssembly

File API

Streams API

Canvas API

OffscreenCanvas

Web Workers

Combined together, they make it possible to process surprisingly complex files without relying on a backend for the conversion itself.

The browser has become much more than a document viewer.

It's a capable application platform.

What If Files Never Left Your Device?

That question became the starting point for our project.

Instead of asking users to upload files, we decided to perform conversions directly inside the browser whenever possible.

That changes the workflow completely.

Instead of:Your Computer ↓ Remote Server ↓ Conversion ↓ Download

The process becomes:Your Computer ↓ Browser ↓ Conversion ↓ Done

No waiting for uploads.

No waiting for downloads.

No wondering where your files are stored.

The Challenges

Of course, building everything inside the browser wasn't easy.

Different file formats require different processing pipelines.

Images behave differently from videos.

Videos behave differently from PDFs.

Audio formats have their own quirks.

Memory usage also becomes important because everything runs on the user's machine.

Some browsers impose limits.

Mobile devices have much less RAM than desktop computers.

Every optimization matters.

The Result

After many iterations, we built a browser-first converter that handles many common file conversions without sending the files to our servers.

The biggest difference isn't the interface.

It's what doesn't happen.

Your files stay where they already are—on your own device.

That means:

better privacy

faster processing for many conversions

no large uploads

no waiting for server queues

fewer concerns about temporary file storage

Lessons We Learned

Building browser-first software changed how we think about web applications.

Not every task belongs on a server anymore.

Modern browsers are capable of much more than many developers realize.

If you're building applications that work with user files, it's worth asking whether the processing really needs to happen remotely.

Sometimes the fastest, simplest, and most privacy-friendly solution is to keep everything local.

Try It Yourself

If you're curious about what browser-based file conversion looks like in practice, we've made our implementation publicly available.

You can try it here:

The Complete Guide to PDF Conversion, Compression, and Editing in 2026

PDF files are one of the most common document formats used today, but they are also one of the most frustrating to work with. While PDFs…

PDF files are used everywhere, but working with them isn’t always simple — especially when it comes to conversion, compression, and editing.

Most of the challenges people face come down to using the wrong workflow for the job.

I wrote a simple guide explaining how PDF conversion, compression, and editing actually work in 2026, and what to watch out for when handling different types of files.
