Gratuit Compresser JPG to Target Size — Hit Exact KB Limits

Compresser any image to an exact kilobyte target with our free Compresser JPG to Size tool on XConverters. Enter a target KB, let iterative compression find the best quality fit, see the result size, and download a JPG — all traité localement dans votre navigateur. Aucun compte, aucun envoi, entièrement gratuit.

Ce que fait cet outil

Many upload forms, job portals, government sites, and exam applications enforce strict file size caps — 200 KB, 500 KB, or similar. Simply lowering quality once rarely hits an exact limit. Iterative compression adjusts quality automatically until the output fits your target, saving frustration when a portal rejects an upload by a few kilobytes.

XConverters lets you type a target size in KB and runs compressToTargetSize logic dans le navigateur. The tool tries successive quality levels until the JPEG falls at or below your limit while staying as visually clear as possible. After processing, it displays the actual result size so you know exactly what you are downloading before you submit to a form.

Processing is entirely local — résumé photos, ID scans, and portfolio images never upload to our servers. There is sans inscription, no watermark, and no daily cap. The output is a standard JPG file named with the achieved size for easy record-keeping.

Extremely small targets on large high-resolution photos may require aggressive compression and visible quality loss. If the tool cannot reach an unrealistically low KB for a huge source, try resizing the image first with our resize tool, then compressing to target.

Formats pris en charge et cas d’usage

Common reasons to compress to a target KB on XConverters:

• Job applications: Fit profile photo limits on hiring portals and ATS systems.
• Government forms: Respectez les exigences de taille des documents numérisés pour les envois en ligne.
• Exam and university portals: Compresser ID photos and signatures to mandated KB caps.

• Visa and passport uploads: Hit embassy website file size limits precisely.
• CMS media libraries: Pre-shrink assets before upload when the admin panel caps file size.

Conseils pour de meilleurs résultats

• Set target slightly below the portal maximum — e.g. 195 KB for a 200 KB limit — to allow metadata overhead.
• Resize very large photos first if the target KB is small relative to resolution.
• Check the displayed result size before downloading — it confirms compliance.
• Use a well-lit, simple background ID photo for better quality at low KB targets.
• Keep the original uncompressed file archived; download a separate compressed copy for submission.
