How much can you compress an image without noticing?
Typical savings ranges, when quality dips, and how to use a live preview instead of guessing.
Most photos can lose 40–80% of their file size at settings that still look sharp on phones and laptops. Flat graphics and already-optimized WebP files may shrink much less. There is no universal “70% quality” that always wins.
Where artifacts show up first
Banding in skies, muddy skin, and soft text appear before you notice anything on a busy product shot. If you see those, raise quality or switch formats instead of dragging the slider to the floor.
- Portraits: stay closer to 80–85% and watch faces at 100% zoom.
- Product photos on white: you can often go lower; watch the edge of the item.
- Screenshots with UI text: prefer PNG or a high WebP — JPG smears type.
- Already-tiny social exports: you may get “already optimal” and should stop.
Use the preview, not a rule of thumb
Filvo shows the new size next to a live preview. Download when savings look good and the preview still matches your bar for quality. For e-commerce, keep a high-quality master and publish a compressed web version so you can re-export later without starting from a muddy file.
The conservative compressor page starts at 85% so you can judge the preview before dropping quality.
Steps
- Upload. Drop the image into the compressor.
- Preview at 100%. Look at gradients, skin, and text — not just the thumbnail.
- Nudge quality. Lower until artifacts appear, then step back one notch.
