Resize the image to the largest dimensions you genuinely need, choose a suitable output format, begin with balanced quality and compare the real result before downloading.
Why image files become large
Image size is influenced by pixel dimensions, file format, visual detail and compression. A photograph that is 6000 pixels wide contains far more information than a website card displayed at 900 pixels. Uploading the full camera file makes visitors download pixels they may never see.
Compression is not one magic percentage. Two files with the same dimensions can respond very differently: a detailed photograph is unlike a simple logo, and an already-compressed JPG may have little unnecessary data left.
Resize before chasing lower quality
First ask where the image will appear. A general web image rarely needs the dimensions of a print photograph. Choose a maximum width that still covers the largest display size you expect, including sharper high-density screens.
- 1200px: useful for ordinary article and card images.
- 1920px: suitable for large desktop or full-HD presentation.
- 2400px: a flexible high-quality starting point.
- 3840px: reserve for cases that genuinely require very large detail.
Choose WebP or JPG
WebP is a strong choice for modern websites and often produces smaller files at comparable visual quality. JPG is widely supported across older software, printing services and communication systems. If compatibility is uncertain, JPG is the safer handoff.
Transparent artwork needs special care. Converting transparent pixels to JPG requires a solid background, because JPG does not preserve transparency.
A practical compression workflow
- Keep an untouched copy of the original.
- Upload the image to MakeLiora Media Optimizer.
- Select the maximum width required.
- Begin near the recommended balanced quality.
- Choose WebP for web use or JPG for broad compatibility.
- Run optimization and compare the original and final file sizes.
- Open the downloaded image at its intended display size and inspect faces, text, gradients and edges.
What visible damage looks like
Excessive compression can produce blocky textures, ringing around text, smeared hair or foliage and bands in smooth skies. If those defects are obvious at the intended viewing size, increase quality. Inspecting at extreme zoom can exaggerate differences that ordinary viewers will never see.
Use the smallest file that still looks appropriate for its actual purpose—not the smallest file the tool can technically produce.
Common image optimization mistakes
- Overwriting the only original file.
- Using a huge image for a small website card.
- Compressing logos and text as if they were photographs.
- Assuming a fixed saving is guaranteed.
- Judging quality only by the percentage slider instead of viewing the output.
Frequently asked questions
Can every image become dramatically smaller?
No. Savings depend on the original format, dimensions and compression. An already-optimised image may change very little.
Is WebP always better than JPG?
WebP often produces smaller web images, but JPG remains more universally compatible. Choose according to where the file will be used.
Does image compression change dimensions?
It can. Quality compression and pixel resizing are separate controls, and combining them often produces the largest practical saving.
