Påverkar bildkomprimering SEO?

Ja — positivt. Komprimerade bilder laddar snabbare, vilket förbättrar Core Web Vitals (särskilt LCP). Snabbare sidor tenderar att rankas bättre i sökmotorer och konvertera fler besökare.

Hur mycket kan jag minska vikten på produktfoton?

Vanligtvis mellan 70 och 85% utan synlig förlust. Ett 4 MB smartphone-foto komprimeras typiskt till 400–700 KB vid 80% kvalitet. Vid konvertering till WebP kan du komma ner till 200–400 KB.

Vilken storlek för Shopify-bilder?

Shopify rekommenderar max 2048×2048 px. Komprimera under 200 KB innan uppladdning — Shopifys CDN serverar nedskalade versioner men kompenserar inte alltid alltför tunga originalfiler.

WebP eller JPG för produktfoton?

WebP är typiskt 25–35% mindre än JPG vid samma kvalitet, med webbläsarstöd över 97% globalt. Använd WebP i din egen butik. Behåll JPG för marknadsplatslistor eller system som kanske inte accepterar WebP.

Kan jag komprimera Shopify-bilder i bulk?

Ja. Släpp din bulk i Zovex (10 gratis, obegränsat i Pro), ladda ner ZIP och ladda upp i Shopify normalt. Ingen tredjepartsserver, inget mellansteg.

Komprimerar Shopify automatiskt?

Shopify nedskalerar och serverar WebP via sitt CDN, men komprimerar inte aggressivt originalfilerna. Förkomprimering före uppladdning minskar bandbredd och ger snabbare sidor.

Laddas mina bilder upp till en server?

Inte med Zovex. Komprimering sker till 100% i din webbläsare via Canvas API. Filerna rör aldrig våra servrar — fullt GDPR-kompatibelt.

Vilken är bästa komprimeringskvaliteten för e-handel?

80–85% är optimalpunkten för produktfoton. Under 75% kan artefakter dyka upp i mjuka övergångar. Över 90% exploderar vikten utan synlig förbättring.

Kan jag komprimera PNG-bilder?

Ja. Zovex komprimerar JPG, PNG, WebP och GIF. PNG bör hållas lossless för logotyper och ikoner med transparens, men du kan också konvertera PNG till WebP för betydligt mindre filer när transparens krävs.

Vad är skillnaden mellan lossy och lossless?

Lossy tar bort omärkbar data och ger filer 5–10× mindre. Lossless bevarar varje pixel men når bara 20–40% reduktion. Använd lossy för produktfoton, lossless för logotyper och ikoner.

Hur skiljer sig Zovex från andra verktyg?

Tre saker: 100% webbläsarbaserad (dina filer lämnar inte enheten), specifikt byggd för e-handel med plattformsförinställningar, och utan uppladdningssteg — bulkar bearbetas i den hastighet din CPU tillåter.

Dina bilder lämnar aldrig din enhet

All komprimering sker till 100% i din webbläsare via Canvas API. Vi laddar aldrig upp, lagrar eller analyserar dina filer.

Why Image Compression Is the #1 E-Commerce SEO Fix

Page speed is one of Google's top ranking factors — and images are responsible for over 50% of a web page's total weight. A slow store doesn't just hurt your SEO rankings. It kills conversions before they happen.

Research from Google shows that 53% of mobile users abandon a page that takes more than 3 seconds to load. For every additional second of load time, conversion rates drop by up to 7%. If you're running a PrestaShop, WooCommerce or Shopify store with hundreds of product images, unoptimised files are costing you money every single day.

Image compression is the single most impactful technical SEO improvement available to most e-commerce stores — and it costs nothing to implement with Zovex.

↑ Better Google rankings ↑ Faster Core Web Vitals ↑ Higher conversion rate ↓ Server & CDN costs ↓ Bandwidth usage

How to Compress Images Without Losing Quality

The key to effective image compression is finding the right balance between file size and visual quality. Zovex uses smart lossy compression that removes invisible data from your images — data the human eye cannot detect at normal viewing distances.

For most product images, a quality setting between 75% and 85% achieves the optimal balance: files that are 60–80% smaller than the original, with no visible quality difference on any screen size.

1
Upload your images

Drag and drop up to 10 images (free plan) or unlimited (Pro). JPG, PNG, WebP and GIF are all supported. No file size limits.

2
Set your quality level

Use the quality slider to choose between maximum compression (smallest file) and maximum quality (sharpest image). The live preview updates instantly — showing exact KB before and after.

3
Download your ZIP

Process your entire batch in seconds. All compressed images are packaged in a ZIP file — ready to upload directly to PrestaShop, WooCommerce, Shopify or any other platform.

Compress Images for PrestaShop, WooCommerce and Shopify

Every e-commerce platform has its own recommended image sizes and quality thresholds. Here are the settings we recommend for the most popular platforms:

PlatformRecommended qualityTarget file sizeBest format
PrestaShop75–85%< 200 KBWebP or JPG
WooCommerce75–85%< 200 KBWebP or JPG
Shopify80–90%< 250 KBWebP or JPG
Amazon85–95%< 500 KBJPG (white bg)
eBay80–90%< 500 KBJPG
Etsy80–85%< 300 KBJPG or WebP

Combining compression with format conversion to WebP will achieve the best results on modern platforms. WebP files are typically 25–35% smaller than equivalent JPG files at the same visual quality.

Image Compression and Google Core Web Vitals

Google's Core Web Vitals are a set of page experience signals that directly influence search rankings. Two of the three Core Web Vitals are directly impacted by image optimisation:

LCP
Largest Contentful Paint

LCP measures how long it takes for the largest visible element on the page to load. On most product pages, this is the main product image. Compressing your hero image is the fastest way to improve your LCP score — and therefore your rankings.

CLS
Cumulative Layout Shift

When images load slowly or without defined dimensions, they cause the page layout to shift as they appear — a poor experience that Google penalises. Properly sized and compressed images load faster and reduce layout shifts.

INP
Interaction to Next Paint

Heavy pages with large uncompressed images take longer to become interactive. Reducing image weight directly improves your store's responsiveness score.

Lossy vs Lossless Compression — Which Should You Use?

Lossy compression (used by Zovex) removes some image data to achieve smaller file sizes — typically reducing files by 60–80% with no visible quality difference at 75–85% quality settings. This is the industry standard for e-commerce product images.

Lossless compression reduces file size without removing any data, achieving more modest reductions (typically 10–30%). This is appropriate for images that require pixel-perfect accuracy — icons, logos with flat colours, and technical diagrams.

For the vast majority of product photography, lossy compression at 75–85% quality is the right choice. Your customers cannot tell the difference, Google cannot tell the difference, but your page speed scores absolutely can.

Frequently Asked Questions

Does compressing images affect SEO?
Yes — positively. Smaller images lead to faster page load times, which is a direct Google ranking signal. Google's Core Web Vitals, specifically LCP and CLS, are directly impacted by image file size. Compressing your product images is one of the fastest and most impactful technical SEO improvements available to any e-commerce store.
How much can I reduce my image file sizes?
Typically 40–80% reduction without visible quality loss. A 2MB product photo compressed at 80% quality will often reduce to 300–500KB — still sharp on any screen, but loading 4–6× faster. WebP conversion combined with compression can achieve even greater reductions.
Are my images uploaded to a server when I compress them?
No. Zovex processes all images 100% inside your browser using the Canvas API. Your files never leave your device. This means zero privacy risk, instant processing, and no waiting for server uploads or downloads — regardless of your internet connection speed.
Can I compress images in bulk for my entire product catalogue?
Yes. The free plan allows up to 10 images per batch. The Pro plan offers unlimited batch processing — ideal for large catalogues with hundreds or thousands of product images. You can combine compression with renaming, resizing and format conversion in a single workflow.
What image formats does the compressor support?
Zovex supports JPG (JPEG), PNG, WebP and GIF compression. For best results, compress and convert JPG and PNG images to WebP simultaneously — you'll achieve the smallest possible file sizes with the highest visual quality.
How do I compress images for Google PageSpeed Insights?
Google PageSpeed Insights recommends serving images in next-gen formats (WebP), sizing images correctly, and efficiently encoding images. Zovex addresses all three: compress your images at 75–85% quality, convert to WebP, and resize to exact display dimensions. This will typically resolve most image-related PageSpeed warnings.
What's the best image compression tool for PrestaShop?
Zovex is specifically designed for e-commerce workflows. It lets you compress, resize and rename your PrestaShop product images in bulk — all in one step, all in your browser. No plugins, no modules, no server-side processing required. Simply compress your images before uploading them to your PrestaShop back office.
