Come funzionano i filtri immagine?
Questo strumento utilizza i filtri CSS dell'API Canvas integrata nel tuo browser per regolare luminosità, contrasto, saturazione e applicare effetti come scala di grigi e seppia. L'intero processo viene eseguito localmente sul tuo dispositivo — le tue immagini non vengono mai inviate a nessun server.
Tips for Applying Image Filters
- Start with subtle adjustments — Small changes to brightness, contrast, and saturation often produce the most natural-looking results.
- Adjust brightness before contrast — Fix brightness first, then fine-tune contrast to bring out details.
- Use grayscale for dramatic effect — Converting to grayscale removes color distractions and emphasizes texture, shape, and composition.
- Combine filters for unique looks — Layer multiple filter adjustments to create custom effects like vintage film looks.
- Use blur for background softening — A slight blur can soften busy backgrounds or create a dreamy aesthetic.
- Preview before downloading — Always check the live preview as you adjust sliders before committing to a download.
- Keep your originals — Filters are applied destructively when you export. Always keep the original file.
When to Apply Filters to Your Images
- Enhancing social media photos — Boost brightness and saturation slightly to make your photos pop in social media feeds.
- Correcting underexposed photos — Increase brightness and reduce contrast slightly to recover detail in dark photos.
- Creating cohesive brand aesthetics — Apply the same filter settings across all your images for a consistent visual style.
- Preparing images for print — Increase contrast and sharpness slightly for images destined for print.
- Black and white photography — Convert color photos to grayscale for artistic portfolios or editorial content.
Domande frequenti
I filtri riducono la qualità?
I filtri vengono applicati matematicamente a ogni pixel e mantengono la piena risoluzione. Per JPEG e WebP, viene utilizzata la codifica al 92% di qualità. L'output PNG è senza perdita.
Posso combinare più filtri?
Sì! Tutti i cursori funzionano insieme. Regola luminosità, contrasto e saturazione contemporaneamente, poi aggiungi scala di grigi, seppia o inversione. Usa il pulsante "Ripristina tutto" per ricominciare.
Quali formati di output sono disponibili?
Puoi esportare la tua immagine filtrata come JPEG, PNG o WebP. Scegli il formato più adatto alle tue esigenze.
Can I reset all filters to the original?
Yes — you can reset all filter sliders back to their default values to return to the original, unfiltered image. Since ImgLab never modifies your source file, you can also simply re-drop the original image to start fresh with a clean slate at any time.
What filter settings work best for social media?
For social media, try increasing brightness by 5–10%, boosting saturation by 10–15%, and adding a small contrast bump of 5–10%. These subtle adjustments make photos look vibrant on mobile screens without appearing over-processed. Avoid heavy blur or extreme saturation changes that look unnatural.
How do I make a photo black and white?
Set the saturation slider to 0% (or use the grayscale toggle if available) to convert your image to black and white. For more dramatic results, also increase contrast by 10–20%. You can create a sepia tone by slightly warming the image after desaturating it.
What is the blur filter useful for?
The blur filter softens the entire image, which is useful for creating background images for text overlays, producing dreamy photo effects, or obscuring sensitive details in screenshots before sharing. For selective blurring (only part of the image), use the Draw tool to paint over specific areas.
