Image Compression & Conversion — Frequently Asked Questions

Honest answers to the questions our users actually ask.

No, and this is the part most people find surprising. Every image you drop into Filecompress.app is handled entirely inside your own web browser using the built-in HTML5 Canvas engine. The picture never leaves your computer or phone, never reaches our servers, and is never written to any database. Two things follow from that. First, your photos stay completely private — we could not look at them even if we wanted to, because we never receive them. Second, the tool keeps working even if your internet drops out halfway through, since all the work happens locally. When you close the tab, the image disappears from memory and there is simply nothing left for anyone to leak or misuse.

You can move freely between JPEG, PNG and WebP, and you can export any of them straight to PDF. As a rough guide: JPEG is the right choice for photographs where a small file matters more than perfect edges; PNG preserves crisp lines and transparency, so it is ideal for logos, icons and screenshots; and WebP usually produces the smallest file at the same visible quality, which makes it the best pick for websites and email. If you are unsure, try WebP first — in most cases it is noticeably lighter than the original with no obvious difference to the eye.

The slider controls how aggressively the encoder throws away information your eyes are least likely to notice. At 100 the file stays large and visually pristine; as you slide down toward 10, the file gets dramatically smaller but compression artefacts (soft blocks around edges, slight colour banding) gradually appear. For everyday use we find the sweet spot sits around 80 to 85 — that typically cuts a photo to a fraction of its original size while keeping it looking clean on screen. The live estimate next to the preview gives you a sense of the result before you commit.

Not if you stay sensible with the settings. Mild to moderate compression removes data selectively and is usually invisible at normal viewing sizes. Blurriness and blocky patches only creep in when you push the quality very low, or when you repeatedly re-compress a file that has already been compressed many times. A good habit is to always start from the highest-quality original you have rather than from a copy that has been saved and re-saved, and to avoid running the same image through heavy compression again and again.

Yes. The Resize tool lets you set a precise width and height in pixels, which is perfect when a platform demands a specific size — a profile photo, a thumbnail, or a banner, for example. The Crop tool lets you trim away the parts of a picture you do not want and keep only the framing you like. Both run in the browser and both can be combined with compression, so you can crop, resize and shrink a picture in a single pass before downloading the finished file.

PNG is a lossless format, which is wonderful for quality but tends to produce large files, especially for detailed photographs. WebP was designed specifically for the modern web and can store the same image with the same visual quality at a much smaller size, often less than half. Smaller images mean faster page loads, lower bandwidth bills and a better experience for visitors on slow connections. Every current browser supports WebP, so for website use it is usually the smarter format.

Choose PDF as the output format and the tool will wrap your image into a clean, properly sized PDF page that is easy to print, email or archive. This is handy for turning a set of scanned receipts, photographed documents or design mock-ups into a single tidy file that opens the same way on every device. Because the conversion happens locally, even sensitive documents like contracts or ID scans never leave your machine.

There is no artificial cap and no daily quota. Since the processing runs on your own device rather than on a shared server, the only real limit is how much memory your browser has available for a single very large image. On a typical laptop or modern phone you can comfortably handle high-resolution photos straight from a camera. You never need an account, you are never asked to pay, and you are never told to come back tomorrow.

In most cases, yes — and that is often a welcome side effect. When the tool re-encodes an image it generally drops the hidden EXIF metadata that cameras and phones attach, which can include GPS coordinates, the device model and the exact time the shot was taken. If you are about to post a picture publicly, running it through the compressor is a simple way to strip out details you might not want strangers to see.
