Invoice Generator & Image Compressor: Free Tools Freelancers Actually Use

Freelancing and running a small shop both come with the same two recurring, unglamorous tasks: getting paid, and getting product or portfolio photos small enough to actually upload. Neither needs dedicated software — the Invoice Generator and Image Compressor handle both in a browser tab, with no monthly subscription attached to either one.

Invoice Generator

The Invoice Generator turns a client name, line items, and a due date into a clean, professional invoice ready to send — built for freelancers and small shops billing a client without dedicated accounting software.

The live preview updates as you type, so what's on screen is exactly what gets exported to PDF — no separate "preview" step that renders differently from the final file.

Add a logo, adjust currency and tax fields, and reuse the same layout invoice after invoice without rebuilding it from scratch each time.

Tip: Give every invoice a sequential number, even as a solo freelancer — it looks more established to clients and makes your own bookkeeping far easier at tax time.

Image Compressor

The Image Compressor shrinks JPG, PNG, and WebP files right in your browser tab, using the Canvas API to re-encode an image at a lower file size while keeping it visually close to the original.

Drag a photo in, adjust the quality slider, and compare the before-and-after file size before downloading — nothing is ever uploaded to a server, which also makes it the fastest way to shrink a photo since there's no upload wait at all.

It's the tool to reach for before adding a product photo to a marketplace listing with a strict size cap, attaching a portfolio image to a client email, or speeding up a personal or shop website.

Tip: Compress product photos to the smallest size that still looks sharp at the display size they'll actually appear at — a listing thumbnail rarely needs a full-resolution original.

A freelancer's two-tab routine

The overlap is less about one feeding into the other and more about both solving the same category of problem: getting the business side of freelance or small-shop work done without buying software for a task that takes two minutes. Compress the product or portfolio photos going out with a proposal, then generate the invoice for the work once it's approved — both in the same free toolkit, both without an account.

Neither tool locks a feature behind a paywall after the first use, which matters for anyone sending invoices or compressing photos regularly rather than as a one-off.

Frequently asked questions

Can the Invoice Generator handle multiple currencies?

Yes — the currency field is adjustable per invoice, so it works for clients billed in a different currency than your own.

Does compressing an image with the Image Compressor reduce its dimensions too?

Only if you choose to — the quality slider reduces file size at the same dimensions by default; resizing is a separate, optional step.

Is client or invoice data saved anywhere after I close the tab?

No — the Invoice Generator processes everything locally in your browser and doesn't store invoice data after the page is closed.

What image formats can the compressor export to?

It compresses JPG, PNG, and WebP files and can export to WebP for the smallest file size at a given quality level.
