Gratuito Comprimir JPG to Target Size — Hit Exact KB Limits

Comprimir any image to an exact kilobyte target with our free Comprimir 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 processado localmente no seu browser. Sem conta, sem carregamento, completamente gratuito.

O que esta ferramenta faz

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 no browser. 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 sem registo, 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.

Formatos suportados e casos de uso

Common reasons to compress to a target KB on XConverters:

• Job applications: Fit profile photo limits on hiring portals and ATS systems.
• Government forms: Cumpra os requisitos de tamanho de documentos digitalizados para submissões online.
• Exam and university portals: Comprimir ID photos and signatures to mandated KB caps.

• CMS media libraries: Pre-shrink assets before upload when the admin panel caps file size.

Dicas para melhores resultados

• 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.
