Ja — positivt. Komprimerede billeder indlæses hurtigere, hvilket forbedrer Core Web Vitals (særligt LCP). Hurtigere sider rangerer typisk bedre i søgemaskiner og konverterer flere besøgende.
Som regel mellem 70 og 85% uden synligt tab. Et 4 MB smartphonefoto komprimeres typisk til 400–700 KB ved 80% kvalitet. Ved konvertering til WebP kan du komme ned til 200–400 KB.
Shopify anbefaler max 2048×2048 px. Komprimer under 200 KB før upload — Shopifys CDN serverer godt nok nedskalerede versioner men kompenserer ikke altid for alt for tunge originaler.
WebP er typisk 25–35% mindre end JPG ved samme kvalitet, med browser-support over 97% globalt. Brug WebP i din egen butik. Hold JPG til markedsplads-listings eller systemer der måske ikke accepterer WebP.
Ja. Slip din bulk i Zovex (10 gratis, ubegrænset i Pro), download ZIP og upload til Shopify normalt. Ingen tredjepartsserver, intet mellemtrin.
Shopify nedskalerer og serverer WebP via sit CDN, men komprimerer ikke aggressivt originalfilerne. Forkomprimering før upload reducerer båndbredde og giver hurtigere sider.
Ikke med Zovex. Komprimering sker 100% i din browser via Canvas API. Filerne rører aldrig vores servere — fuldt GDPR-kompatibelt.
80–85% er sweet-spottet for produktfotos. Under 75% kan artefakter dukke op i bløde gradienter. Over 90% eksploderer vægten uden synlig forbedring.
Ja. Zovex komprimerer JPG, PNG, WebP og GIF. PNG bør holdes lossless til logoer og ikoner med transparens, men du kan også konvertere PNG til WebP for væsentligt mindre filer når der kræves transparens.
Lossy fjerner umærkelige data og giver 5–10× mindre filer. Lossless bevarer hver pixel men når kun 20–40% reduktion. Brug lossy til produktfotos, lossless til logoer og ikoner.
Tre ting: 100% browser-baseret (dine filer forlader ikke enheden), specifikt bygget til e-handel med platformforudindstillinger, og uden upload-trin — bulks behandles med den hastighed din CPU tillader.
Al komprimering sker 100% i din browser via Canvas API. Vi uploader, gemmer eller analyserer aldrig dine filer.
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.
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.
Drag and drop up to 10 images (free plan) or unlimited (Pro). JPG, PNG, WebP and GIF are all supported. No file size limits.
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.
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.
Every e-commerce platform has its own recommended image sizes and quality thresholds. Here are the settings we recommend for the most popular platforms:
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.
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 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.
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.
Heavy pages with large uncompressed images take longer to become interactive. Reducing image weight directly improves your store's responsiveness score.
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.
