Frequently Asked Questions
Complete Guide: Image Compressor
What is Image Compressor?
FlikTools Image Compressor reduces the file size of JPG, PNG, and WebP images while keeping them visually identical to the original. The compression runs entirely in your browser, so your photos never leave your device.
Compression and resizing are different jobs. Compression keeps the same pixel dimensions but rewrites the image data more efficiently — perfect when you need a smaller file but the same on-screen size. A 5 MB photo can typically be cut to under 1 MB with no visible quality loss.
It's used by bloggers speeding up their pages, e-commerce sellers cutting CDN bills, designers emailing mockups, and anyone who's ever had an upload form complain that their image is too large.
When Should You Use Image Compressor?
- Speeding up your website. Image weight is the #1 cause of slow page loads. Compress every image before upload to improve Core Web Vitals.
- Email and messaging attachments. Send photo galleries without hitting attachment limits or making recipients wait on downloads.
- Cloud storage savings. Cut your Google Drive or iCloud usage by compressing photo libraries before backup.
- Job and visa applications. Most upload forms cap each photo at 1–2 MB — compression makes raw camera images fit.
- Design handoff. Share Figma exports or mockups without sending massive files over Slack.
Image Compressor vs Other Tools
Compared to TinyPNG or other server-side compressors, FlikTools never uploads your images — the compression happens locally, so there's no privacy concern and no monthly file limit. Compared to desktop apps, there's nothing to install and it works on phones too.
If you want to compress images online for free without trading away your photos, this is the most practical option.
Tips for Best Results
- Compress before resizing. If you also need a smaller resolution, run Image Resizer first, then compress for the smallest possible final file.
- Use WebP when supported. WebP typically beats JPG by 25–35% at the same quality — switch when the destination supports it.
- Don't double-compress. Repeatedly compressing the same JPG slowly degrades it. Always compress from the original.
- Batch on a fast device. Browser compression uses your device's CPU — compressing 50 photos is much faster on a laptop than on a phone.
