Own web tool

Smaller images. Files stay yours.

Kompres processes a whole batch in the browser, with separate presets for email and websites. Images never leave the device.

One tool, two real jobs.

01

Email mode

Produces JPEG and PNG files that email clients display directly and keeps the total attachment size in view.

02

Website mode

Creates WebP and AVIF files, with size and quality controls for use on a website.

03

Batch processing

Multiple images run through Web Workers, so the interface stays responsive while codecs do the heavy work.

Technical decisions

Processing stays on the device.

No upload

JPEG, PNG, WebP and AVIF codecs run locally. The server delivers the app but never receives the user's images.

Installable PWA

The Vite build includes a service worker and can be added to the home screen for repeat use.

Terms of Service

Last updated: 7 October 2026.

These terms describe how we work together. They're written in plain language — if anything is unclear, just ask.

Who provides the service

The service is provided by SGLASSSERVICE - 016 DOO OGRANAK RAČUNSKO PROGRAMIRANJE BOŠNJACE, and the sites and apps are built by me, D. Svilenković. Contact: dimitrije@svilenkovic.com, +381 61 224 8989.

What I do

I build websites, web and desktop apps, online stores, Excel automation, appointment booking, system integrations, hosting and maintenance.

How we agree on work

  1. You tell me what you need. The conversation is non-binding.
  2. I send you a quote with the price and the timeline.
  3. When you confirm the quote, I start development.

Price and payment

The price is fixed and agreed upfront. The invoice is issued only after you confirm you're happy with the result. If the scope changes significantly, we agree on the new price before continuing.

Timelines

I give a deadline in the quote and stick to it. If I need material from you (images, text, access), please send it on time, because the deadline depends on it.

Revisions

Small revisions are included and done at no charge. Larger changes that go beyond the original scope are agreed separately.

Ownership

Once paid, everything I built is yours. You can use it, change it or move it to another developer without involving me.

Hosting and maintenance

The first year of hosting and maintenance is included. After that, if you want to continue, we agree on a support plan. You can move the site to another host at any time.

Liability

I do my best to make everything work as it should, but bugs happen. As soon as you report one, I fix it as fast as possible. My liability is limited to the amount paid for the project.

Cancellation

You can cancel at any time. You pay only for the work done up to that point, and receive all the materials and code you've paid for.

Disputes

If a disagreement arises, we'll first try to resolve it by talking. If that fails, the law of the Republic of Serbia applies and the court at the provider's seat is competent.

Changes to these terms

These terms may be updated. The last-updated date is shown at the top — you can always see what currently applies.
