Images
Pour quoi faire?
Format et qualité
Plus bas : plus léger. Plus haut : plus fidèle.
Taille
L’image remplit tout le cadre, centrée ; le surplus est coupé (comme un recadrage automatique).
Une image n’est jamais agrandie (sauf en réseaux sociaux, où la taille est fixe). Les données cachées (lieu de la prise de vue, appareil) sont retirées.
Noms des fichiers
Exemplemarque-sujet-lieu-01.webp
Minuscules, sans accents ni espaces, avec des tirets : ce que lisent les moteurs de recherche.
Aucune image pour l’instant. Déposez-en n’importe où sur cette page, ou ouvrez « Images » à gauche pour les choisir.
Drop your photos, choose what they are for, download. Images are converted on your computer, in batches, and come out lighter, in the right format and with clean names for Google.
How it works
- Drop your images in the box, or click to choose them. You can add as many as you like.
- Choose the use (original size, website, shop, social media, email): format, size and quality are set for you. Adjust quality, size or file names if needed.
- Download each image or the whole batch. In Easy mode they are ready right away; in Manual mode, click “Convert” first.
Easy or manual
To convert quickly: drop your files and choose what they are for. Everything else is set for you.
To set everything yourself: format, quality, sizes, file names. Your choices are kept for next time.
Good to know
Input: JPG, PNG, WebP, AVIF, GIF, SVG, TIF and HEIC (iPhone photos). Output: WebP (the best choice for a website), AVIF (even lighter), JPG (accepted everywhere), PNG (lossless, for logos), SVG (tracing a logo or an illustration) and ICO (favicon). Images are never enlarged, except SVGs, and hidden data (location, camera) is removed.
Frequently asked questions
Which format should I use for a website?
WebP in almost every case: 25 to 35% lighter than JPG and supported by every current browser. AVIF is even lighter but slower to make. Keep PNG for a logo that must stay perfectly sharp.
How many images can I convert at once?
As many as your computer can handle: they are processed one after the other and downloaded together as a zip, with a summary spreadsheet.
Are my files uploaded to a server?
No. The conversion is done by your browser, on your computer: no file ever leaves your device. You can even go offline once the page has loaded.
Is it free?
Yes: no sign-up, no limit on the number of files and no watermark.
